1. INTRODUCTION

Once, being in nature, we observed a rather beautiful phenomenon - a rainbow. The beauty of this phenomenon simply fascinated us. We had quite a lot of surveys, which we later formulated in our project.

Project goals:

Understand how a rainbow is formed.

Why does it always form at the same angle?

Why is the rainbow shaped like an arc?

Rainbow: main and side. What is the difference?

Why is the name of Isaac Newton associated with the rainbow in the scientific world?

And so our research began.

2.WHAT IS A RAINBOW

The rainbow is not an object at all, but optical phenomenon. This phenomenon occurs due to the refraction of light rays in drops of water, and all this only during rain. That is, a rainbow is not an object, but just a play of light. But what a beautiful game, I must say!

In fact, the arc familiar to the human eye is only a part of a multi-colored circle. In its entirety, this natural phenomenon can only be seen from the aircraft, and even then only with a sufficient degree of observation.

The first studies of the shape of the rainbow were carried out in the 17th century by the French philosopher and mathematician René Descartes. For this, the scientist used a glass ball filled with water, which made it possible to imagine how the sun's ray is reflected in a raindrop, refracted and thereby becoming visible.

To remember the sequence of colors in the rainbow (or spectrum), there are special simple phrases - in them the first letters correspond to the first letters of the color names:

To akO onceAND and to -Z vonarG tinFROM brokeF onar.

To everyO hotnikAND doesZ natG deFROM goesF azan

Memorize them - and you can easily draw a rainbow at any time!

The first to explain the nature of the rainbow wasAristotle . He determined that "a rainbow is an optical phenomenon, not a material object."

An elementary explanation of the phenomenon of the rainbow was given as early as 1611 by A. de Dominy in his work "De Radiis Visus et Lucis", then developed by Descartes ("Les météores", 1637) and fully developed by Newton in his "Optics" (1750) .

The rainbow from one drop is weak, and in nature it cannot be seen separately, since there are many drops in the curtain of rain. The rainbow that we see in the sky is formed by myriads of drops. Each drop creates a series of nested colored funnels (or cones). But from a single drop, only one colored ray enters the rainbow. The observer's eye is a common point at which colored rays from many drops intersect. For example, all the red rays that come out of different drops, but at the same angle and hit the observer's eye, form a red arc of the rainbow. All orange and other colored rays also form arcs. Therefore, the rainbow is round.

3. RAINBOW IN MYTHOLOGY AND RELIGION

People have long thought about the nature of this most beautiful natural phenomenon. Humanity has associated the rainbow with many beliefs and legends. In ancient Greek mythology, for example, a rainbow is the road between heaven and earth, along which the messenger between the world of the gods and the world of people, Irida, walked. In China, it was believed that the rainbow is a heavenly dragon, the union of Heaven and Earth. In Slavic myths and legends, a rainbow was considered a magical heavenly bridge thrown from heaven to earth, a road along which angels descend from heaven to draw water from rivers. They pour this water into the clouds and from there it falls as life-giving rain.

Superstitious people believed that the rainbow is a bad sign. They believed that the souls of the dead pass into the other world along the rainbow, and if a rainbow appeared, this means someone's imminent death.

Of course, since ancient times, people have tried to explain the rainbow. In Africa, for example, it was believed that a rainbow is a huge snake that periodically crawls out of oblivion to perform its dark deeds. However, intelligible explanations regarding this optical miracle could only be given towards the end of the seventeenth century. Then the famous Rene Descartes lived little by little. It was he who was the first to be able to simulate the refraction of rays in a water drop. In his research, Descartes used a glass ball filled with water. However, until the end, he could not explain the secret of the rainbow. But Newton, who replaced this very ball with a prism, managed to decompose a beam of light into a spectrum.

SUMMARY:

The rainbow is a bridge connecting (the world of people) and (the world of the gods).

In ancient Indian - bow, the god of thunder and lightning.

B - road, messengers between the worlds of gods and people.

According to legend, a rainbow, like a snake, drinks water from lakes, rivers and seas, which then rains.

Hides a pot of gold in the place where the rainbow touched the ground.

According to popular beliefs, if you pass through a rainbow, you can change gender.

The rainbow appeared later as a symbol of the forgiveness of mankind, and is a symbol of the union (in Hebrew - Brit) of God and mankind (in the person of Noah) that the flood will never happen again. (Hebrew chapter)

4.HISTORY OF RAINBOW RESEARCH

The Persian astronomer (1236-1311), and perhaps his student (1260-1320), was apparently the first to give a fairly accurate explanation of the phenomenon.

The general physical picture of the rainbow was described in the book De radiis visus et lucis in vitris perspectivis et iride. On the basis of experimental observations, he came to the conclusion that a rainbow is obtained as a result of reflection from the inner surface of a rain drop and double refraction - when entering the drop and exiting it.

He gave a more complete explanation of the rainbow in the year in his work "Meteors" in the chapter "On the Rainbow".

Although the multi-color spectrum of the rainbow is continuous, there are 7 colors in it. It is believed that he was the first to choose the number 7, for which the number had a special meaning (for, or reasons). Moreover, initially he distinguished only five colors - red, yellow, green, blue and violet, which he wrote about in his Optics. But later, trying to create a correspondence between the number of colors of the spectrum and the number of fundamental tones of the musical scale, Newton added to the five listed two more colors of the spectrum.

5. RAINBOW PHYSICS

5.1. Where does the rainbow come from? Observation conditions

Rainbows can only be seen before or after rain. And only if, simultaneously with the rain, the sun breaks through the clouds, when the sun illuminates the veil of falling rain and the observer is between the sun and the rain. What is happening? The rays of the sun pass through the raindrops. And each such droplet works like a prism. That is, it decomposes the white light of the Sun into its components - the rays of red, orange, yellow, green, deep, blue and violet. Moreover, droplets deflect light of different colors in different ways, as a result of which white light decomposes into a multi-colored band, which is calledspectrum .

You can only see a rainbow if you are directly between the sun (it should be behind you) and the rain (it should be in front of you). Otherwise, you won't see the rainbow!

Sometimes, very rarely, a rainbow is observed under the same conditions and when a rain cloud is illuminated by the moon. The same phenomenon of a rainbow is sometimes noticed when the sun illuminates water dust that is carried in the air near a fountain or waterfall. When the sun is covered with light clouds, the first rainbow sometimes seems completely uncolored and appears as a whitish arc, lighter than the background of the sky; such a rainbow is called white.

Observations of the phenomenon of the rainbow have shown that its arcs represent regular parts of circles, the center of which always lies on a line passing through the head of the observer and the sun; since in this way the center of the rainbow lies below the horizon with a high sun, the observer sees only a small part of the arc; at sunset and sunrise, when the sun is on the horizon, the rainbow appears as a half-arc of a circle. From the very top high mountains, from a balloon you can see the rainbow in the form of most of the arc of a circle, since under these conditions the center of the rainbow is located above the visible horizon.

CONCLUSION: A rainbow appears only when suitable conditions are created for this. Sunlight should shine at your back, and raindrops should fall somewhere ahead. (Because a rainbow needs a bright sunlight, this means that the downpour has already gone further or even passed by, and you are facing it.)

5.2. Why is the rainbow shaped like an arc.

Why is the rainbow semicircular? People have been asking this question for a long time. In some African myths, a rainbow is a snake that encircles the Earth in a ring. But now we know that a rainbow is an optical phenomenon - the result of the refraction of light rays in water droplets during rain. But why do we see the rainbow in the form of an arc, and not, for example, in the form of a vertical colored stripe?

Here the law of optical refraction comes into force, in which the beam, passing through a raindrop located in a certain position in space, undergoes 42-fold refraction and becomes visible to the human eye precisely in the form of a circle. Here is just a part of this circle you are accustomed to observe.

The shape of a rainbow is determined by the shape of the water droplets in which sunlight is refracted. And water droplets are more or less spherical (round). Passing through the drop and being refracted in it, a bunch of white sun rays is transformed into a series of colored funnels inserted one into the other, facing the observer. The outer funnel is red, orange is inserted into it, yellow, then comes green, etc., ending with the inner violet. Thus, each individual drop forms a whole rainbow.

Of course, the rainbow from one drop is weak, and in nature it is impossible to see it separately, since there are many drops in the curtain of rain. The rainbow that we see in the sky is formed by myriads of drops. Each drop creates a series of nested colored funnels (or cones). But from a single drop, only one colored ray enters the rainbow. The observer's eye is a common point at which colored rays from many drops intersect. For example, all the red rays that come out of different drops, but at the same angle and hit the observer's eye, form a red arc of the rainbow. All orange and other colored rays also form arcs. Therefore, the rainbow is round.

The rainbow is a huge curved spectrum. To an observer on the ground, a rainbow usually looks like an arc - part of a circle, and the higher the observer is, the fuller the rainbow. From a mountain or an airplane, you can also see the full circle!

It is interesting to note that two people standing side by side and observing a rainbow see it each in their own way! All this is due to the fact that at every single moment of viewing, a rainbow is constantly formed in new drops of water. That is, one drop falls, and another appears instead. Also, the appearance and color of the rainbow depends on the size of the water droplets. The larger the raindrops, the brighter the rainbow will be. The most intense color in the rainbow is red. If the drops are small, then the rainbow will be wider with a pronounced orange color on the edge. I must say that we perceive the longest wavelength of light as red, and the shortest - as violet. This applies not only to cases of observing the rainbow, but in general to everything and everyone. That is, you can now intelligently comment on the state, size and color of the rainbow, as well as all other objects visible to the human eye.

Two people standing side by side see each their own rainbow! Because at every moment the rainbow is formed by the refraction of the sun's rays in new and new drops. Raindrops are falling. The place of the fallen drop is occupied by another and manages to send its colored rays to the rainbow, followed by the next one, and so on.

The type of rainbow also depends on the shape of the drops. When falling in the air, large drops are flattened and lose their sphericity. The stronger the flattening of the droplets, the smaller the radius of the rainbow they form.

There is a group of optical phenomena called halo. They are caused by the refraction of light rays by tiny ice crystals in cirrus clouds and mists. Most often, halos form around the Sun or Moon. Here is an example of such a phenomenon - a spherical rainbow around the Sun:

In fact, a rainbow is not a semicircle, but a circle. It’s just that we don’t see it in full, because the center of the rainbow circle lies on the same line as our eyes. For example, from an airplane you can see a full, round rainbow, although this is extremely rare, because on airplanes they usually look at beautiful neighbors, or eat hamburgers while playing AngryBirds. So why is the rainbow shaped like a semicircle? All this is because the raindrops that form a rainbow are clumps of water with a rounded surface. The light coming out of this very drop reflects its surface. That's the whole secret.

CONCLUSION: The type of rainbow also depends on the shape of the drops. When falling in the air, large drops are flattened and lose their sphericity. The stronger the flattening of the droplets, the smaller the radius of the rainbow they form. The arc of the rainbow is just a segment of the circle of light, in the center of the viewing sector of which is the observer, that is, you. And the higher you stand, the more complete the rainbow will be

The type of rainbow - the width of the arcs, the presence, location and brightness of individual color tones, the position of additional arcs - is very dependent on the size of the raindrops. The larger the raindrops, the narrower and brighter the rainbow is. Characteristic of large drops is the presence of saturated red color in the main rainbow. Numerous additional arcs also have bright colors and directly, without gaps, adjoin the main rainbows. The smaller the droplets, the wider and faded the rainbow with an orange or yellow edge. Additional arcs are further apart both from each other and from the main rainbows. Thus, by the appearance of the rainbow, one can approximately estimate the size of the raindrops that formed this rainbow.

5.3 Rainbow coloration and secondary rainbow

The color of the rainbow ring is caused by the refraction of sunlight in spherical raindrops, their reflection from the surface of the drops, as well as diffraction (from Latin diffractus - broken) and interference (from Latin inter - mutually and ferio - hit) reflected rays of different wavelengths.

Sometimes you can see another, less bright rainbow around the first one. This is a secondary rainbow in which the light is reflected twice in the drop. In the secondary rainbow, the “inverted” order of colors is purple on the outside, and red on the inside:

The inner, most often visible arc is colored red from the outer edge, purple from the inner; between them in the usual order of the solar spectrum are the colors: (red), orange, yellow, green, blue and violet. The second, less frequently observed arc lies above the first, is usually more weakly colored, and the order of the colors in it is reversed. The part of the firmament inside the first arc usually appears very bright, the part of the firmament above the second arc appears less bright, while the annular space between the arcs appears dark. Sometimes, in addition to these two main elements of the rainbow, additional arcs are observed, representing faint colored fuzzy bands bordering the upper part. inner edge of the first rainbow and less often - the upper part of the outer edge of the second rainbow

Sometimes you can see another, less bright rainbow around the first one. This is a secondary rainbow in which the light is reflected twice in the drop. In the secondary rainbow, the “inverted” order of colors is on the outside, and red on the inside. The angular radius of the secondary rainbow is 50-53°. The sky between two rainbows usually has a noticeably darker hue.

In the mountains and other places where it is very fresh air, a third rainbow can be observed (angular radius of about 60°).

Blurring and blurring of the colors of the rainbow is explained by the fact that the source of illumination is not a point, but the whole surface - the sun, and that separate sharper rainbows formed by individual points of the sun are superimposed on each other. If the sun shines through a veil of thin clouds, then the luminous source is a cloud surrounding the sun for 2-3 ° and the individual colored bands are so superimposed on each other that the eye no longer distinguishes colors, but sees only a colorless light arc -white rainbow.

Since raindrops increase as they approach the earth, additional rainbows can be clearly visible only when light is refracted and reflected in high layers of the rain veil, that is, at a low sun height and only at the upper parts of the first and second rainbows. A complete theory of the white rainbow was given by Pertner in 1897. The question has often been raised whether different observers see the same rainbow and whether a rainbow seen in the still mirror of a large water reservoir represents a reflection of a directly observed rainbow.

CONCLUSION: A rainbow occurs when the sun experiences in water droplets slowly falling into. These droplets are different, causing the light to decompose into. It seems to us that a multi-colored glow emanates from space along concentric () . In this case, the source of bright light is always located behind the back of the observer. Later measured, which deviates by 137 30 minutes, and by 139 ° 20 ')

5.4. The reason for the rainbow is the refraction and dispersion of light

Quite simply: Simply put, the appearance of a rainbow can be derived in the following formula: light passing through raindrops is refracted. And it refracts because water has a higher density than air. White color, as you know, consists of seven primary colors. It is quite clear that all colors have different wavelengths. And this is where the whole secret lies. When a sunbeam passes through a drop of water, it refracts each wave differently.

And now in more detail.

5.4.1. EXPERIMENTS OF NEWTON

Newton, when improving optical instruments, noticed that the image was painted at the edges in an iridescent color. He was interested in this phenomenon. He began to explore it in more detail. Ordinary white light was passed through the prism, and a spectrum similar to the colors of the rainbow could be observed on the screen. At first, Newton thought that it was the prism that colored the white. As a result of numerous experiments, it was possible to find out that the prism does not color, but decomposes the white color into a spectrum.

CONCLUSION: rays of different colors come out of the prism at different angles.

5.4.2. "NEWTON" IN DROPS

When passing through raindrops, light is refracted (bent to the side) because the water has more high density than air. It is known that the white color consists of seven primary colors - red, orange, yellow, green, blue, indigo and violet. These colors have different wavelengths, and the drop refracts each wave to a different degree as the sun's ray passes through it. Thus, the waves are of different lengths and, therefore, the colors come out of the drop already in slightly different directions. What was at first a single beam of rays has now disintegrated into its natural colors, each traveling its own path.

Colored rays, hitting the inner wall of the drop and bending even more, can even go out through the same side as they entered. And as a result, you see how the rainbow scattered its colors across the sky in an arc.

Each drop reflects all colors. But from your fixed position on earth, you only perceive certain colors from certain drops. The droplets reflect red and orange colors most clearly, so they reach your eyes from the topmost droplets. Blues and violets are less reflective, so you see them from the droplets a little lower. Yellow and green reflect the drops that are in the middle. Put all the colors together and you have a rainbow.

Most often observedprimary rainbow where light undergoes one internal reflection. The path of the rays is shown in the figure at the top right. In the primary rainbow, it is located outside the arc, its angular is 40-42 °.

PHYSICAL EXPLANATION

Observations over the rainbow have shown that the angle formed by two lines mentally drawn from the observer's eyes to the center of the arc of the rainbow and to its circumference, or the angular radius of the rainbow, is an approximately constant value and equal to about 41 ° for the first rainbow, 52 ° for the second. An elementary explanation of the phenomenon of the rainbow was given as early as 1611 by A. de Dominy in his work "De Radiis Visus et Lucis", then developed by Descartes ("Les météores", 1637) and fully developed by Newton in his "Optics" (1750) . According to this explanation, the phenomenon of the rainbow occurs due to the refraction and total internal reflection (see Dioptric) of the sun's rays in raindrops. If a ray SA falls on a spherical drop of liquid, then (Fig. 1), having undergone refraction in the direction AB, it can be reflected from the back surface of the drop in the direction BC and exit, again being refracted, in the direction CD.

The beam, which otherwise fell on the drop, can, however, at point C (Fig. 2) be reflected a second time along CD and exit, refracted, in the direction DE.

If not one ray, but a whole beam of parallel rays falls on the drop, then, as is proved in optics, all the rays that have undergone one internal reflection in the water drop will emerge from the drop in the form of a diverging cone of rays (Fig. 3), the axis of which is located along in the direction of the incident rays. In fact, the beam of rays emerging from the drop does not represent a regular cone, and even all the rays that make it up do not intersect at one point, only for simplicity in the following drawings these beams are taken as regular cones with a vertex in the center of the drop

The opening angle of the cone depends on the refractive index (see Dioptric) of the liquid, and since the refractive index for rays various colors(of different wavelengths) that make up the white sunbeam is not the same, then the angle of the opening of the cone will be different for rays of different colors, it will be less for violet than for red. As a result, the cone will be bordered by a colored rainbow edge, red from the outside, purple inside, and if the drop is water, then half of the corner hole of the coneSOR for red it will be about 42 °, for purple (SOV ) 40.5°. A study of the distribution of light inside the cone shows that almost all the light is concentrated in this colored border of the cone and is extremely weak in its central parts; thus, we can only consider the bright colored shell of the cone, since all its internal rays are too weak to be perceived by sight.

A similar study of rays reflected twice in a drop of water will show us that they will emerge in the same conical iris.V"R" (Fig. 3), but red from the inner edge, purple from the outer, and for a water drop, half of the corner hole of the second cone will be equal to 50 ° for red (SOR" ) and 54° for the purple edge (SOV ) .

Imagine now that the observer whose eye is at the pointO (fig. 4), looking at a row of vertical raindropsA, B , C, D, E... , illuminated by parallel rays of the sun going in the directionSA, SB, SC etc.; let all these drops be located in a plane passing through the eye of the observer and the sun; each such drop will, according to the previous one, emit two conical light shells, the common axis of which will be the sunbeam falling on the drop.

Let the dropAT located so that one of the rays forming the inner shell of the first (inner) cone, when continued, will pass through the eye of the observer; then the observer will seeAT purple dot. A little higher than a dropAT drop C will be located such that the beam coming from the outer surface of the shell of the first cone will enter the eye and give it the impression of a red dot inFROM ; drops intermediate betweenAT andFROM, will give the eye the impression of dots of blue, green, yellow and orange. In sum, the eye will see in this plane a vertical rainbow line with a violet end at the bottom and a red one at the top; if we go throughO and sun lineSO then the angle formed by it with the lineOV , will be equal to the half-hole of the first cone for violet rays, i.e. 40.5 °, and the angleKOS will be equal to the half-opening of the first cone for red rays, i.e. 42 °. If you turn the cornerKOV aroundOK, thenOB will describe a conical surface and each drop lying on the circle of intersection of this surface with a rain veil will give the impression of a bright purple point, and all the points together will give a purple arc of a circle centered atTo ; in the same way, red and intermediate arcs are formed, and in total the eye will receive the impression of a light rainbow arc, purple inside, red outside -first rainbow.

Applying the same reasoning to the second outer light cone shell emitted by drops and formed by solar rays reflected twice in a drop, we obtain a widersecond concentricrainbow with an angleCFU, equal for the inner red edge - 50 °, and for the outer purple - 54 °. Due to the double reflection of light in the drops that give this second rainbow, it will be much less bright than the first. DropsD, lying betweenFROM andE, they do not emit light at all into the eye, and therefore the space between the two rainbows will appear dark; from the drops belowAT and higherE, white rays will enter the eye, emanating from the central parts of the cones and therefore very weak; this explains why the space under the first and above the second rainbow seems to us dimly lit.

CONCLUSION:The elementary theory of the rainbow clearly indicates that different observers see rainbows formed by different raindrops, i.e., different rainbows, and that the apparent reflection of a rainbow is that rainbow that an observer would see if placed under a reflecting surface at such a distance down from it, at what he is above her. Observed in rare cases, especially at sea, intersecting eccentric rainbows are explained by the reflection of light from the water surface behind the observer and the appearance, thus, of two sources of light (the sun and its reflection), each giving its own rainbow.- does not perceive). Therefore, the lunar rainbow looks whitish; but the brighter the light, the more "colorful" the rainbow will be, because in humans, bright light turns on the perception of color receptors -.

The center of the circle described by the rainbow always lies on a straight line passing through (the moon) and the eye of the observer, that is, it is impossible to see the sun and the rainbow at the same time without using mirrors. For an observer on the ground, it usually looks like part of a circle, the higher the point of view, the fuller the rainbow - from a mountain or an airplane you can see the whole .

A simple rainbow-arc is usually observed, but under certain circumstances you can see a double rainbow, and from an airplane - an inverted or even annular one.

We are accustomed to seeing the rainbow as an arc. In fact, this arc is only part of a multi-colored circle. In its entirety, this natural phenomenon can only be observed at high altitude, for example, from an airplane.

There is such a group of optical phenomena, which is called a halo. They are caused by the refraction of light rays by tiny ice crystals in cirrus clouds and mists. Most often, halos form around the Sun or Moon. Here is an example of such a phenomenon - a spherical rainbow around the Sun: Iris resembles rainbow sectors

The rainbow also appears in many folk omens associated with weather forecasting. For example, a high and steep rainbow portends good weather, while a low and flat one portends bad weather.

caregiver: Guys, look at the reproductions of famous artists. What do you see in all these pictures?

Children: rainbow

caregiver: Does anyone know what such a rainbow and how does it appear?

Children answer that it appears after the rain, when the sun is shining.

caregiver: Rainbow- one of the most beautiful phenomena of nature.

Have you guys ever seen rainbow?

What does she look like?

The teacher listens to the answers children: On the rocker, on the arc, on the bridge, etc.

caregiver: Since ancient times, man has thought about the nature of origin rainbows and associated the appearance of a multi-colored arc in the sky with many beliefs and legends. Some thought that the rainbow is the heavenly bridge, from which gods or angels descended to earth, others said that this was the road between heaven and earth or from the gate to another other world.

In fact, rainbow- this is atmospheric phenomenon, which is observed when the Sun illuminates many water droplets during rain or fog, or after rain. When the sun's rays are refracted in water droplets during rain, a multi-colored arc appears in the sky.

And let's remember how many colors it has rainbow and what?

Children: 7 colors, list colors, remembering a famous rhyme: "Every hunter wants to know where his pheasant is sitting".

caregiver: Now we will try to create our own rainbow

An experience « rainbow film»

Put a bowl of water on the table so that direct rays of light do not fall on it. Hold a brush from a bottle of varnish over a bowl until a drop of varnish falls into the water. Watch the surface of the water. Move your head to look at the water different points. What did we see?

On a thin layer of varnish spilled over the water, iridescent play. The varnish forms a thin film on the surface of the water. When light falls on the surface of this film, each of its rays is partially reflected from it. The other part of the beam reaches the bottom surface of the film and is also reflected from it. The reflections of the rays add up to each other, and we can see the overflows rainbow tones.

We only have 4 colors: red, yellow, blue, white.

How can we draw rainbow?

Children offer their own options for mixing colors.

caregiver: Let's check your answers. We have red, orange = red + yellow, yellow - yes, green = blue + yellow, blue = blue + white, blue yes, purple = blue + red.

I invite everyone to draw their own rainbow, just do not confuse the arrangement of flowers.

And in the end lessons, we will again play with soap bubbles. After releasing bubbles, carefully look at them. Each bubble has Iris, which also includes all colors.

Rainbow is one of the most amazing phenomena nature. What is a rainbow? How does she appear? These questions have interested people at all times. Even Aristotle tried to unravel its mystery. There are many beliefs and legends associated with it (the road to the next world, the connection between heaven and earth, a symbol of abundance, etc.). Some peoples believed that the one who passes under the rainbow will change their gender.

Her beauty amazes and delights. Looking at this colorful "magic bridge", I want to believe in miracles. The appearance of a rainbow in the sky notifies that the bad weather is over and a clear sunny time has come.

When does a rainbow happen? It can be observed during rain or after a downpour. But for its occurrence, lightning and thunder are not enough. It appears only if the sun breaks through the clouds. Certain conditions are needed in order for it to be noticed. It is necessary to be between the rain (it should be in front) and the sun (it should be behind). Your eyes, the center of the rainbow and the sun must be on the same line, otherwise this magic bridge you can't see!

Surely many have noticed what happens when a ray falls on a soap bubble or on the edge of a beveled mirror. It is divided into various colors (green, blue, red, yellow, purple, etc.). The object that breaks the beam into its component colors is called a prism. And the resulting multi-colored line is a spectrum.

So what is a curved spectrum, a colored band formed as a result of the separation of a beam of light when passing through raindrops (they are a prism in this case).

The colors of the solar spectrum are arranged in a certain order. On the one hand - red, then orange, next to it - yellow, green, blue, blue, purple. The rainbow is clearly visible as long as the raindrops fall evenly and frequently. The more often, the brighter it is. Thus, three processes occur simultaneously in a raindrop: refraction, reflection and decomposition of light.

Where to see a rainbow? At fountains, waterfalls, against the background of drops, splashes, etc. Its location in the sky depends on the position of the sun. You can admire the entire rainbow circle if you are high in the sky. The higher the sun rises above the horizon, the smaller the colored semicircle becomes.

The first attempt to explain what a rainbow is was made in 1611 by Antonio Dominis. His explanation was different from the biblical one, so he was sentenced to death. In 1637, Descartes gave a scientific phenomenon based on the refraction and reflection of sunlight. At that time, they did not yet know about the decomposition of the beam into a spectrum, that is, dispersion. Therefore, Descartes' rainbow turned out to be white. After 30 years, Newton "colored" it, supplementing his colleague's theory with explanations of the refraction of colored rays in raindrops. Despite the fact that the theory is more than 300 years old, it correctly formulates what a rainbow is, its main features (arrangement of colors, position of arcs, angular parameters).

It is amazing how light and water, which are familiar to us, create together a completely new, unimaginable beauty, a work of art given to us by nature. Rainbow always causes a surge of emotions and remains in memory for a long time.

1. Introduction.

Rainbow is one of the most beautiful natural phenomena. Once, walking after the rain, I saw a rainbow in the sky. I was in awe of what I saw. And immediately questions began to arise: how is such beauty obtained, and is it possible to do all this at home in order to see this amazing miracle again?

In addition, in the traditional symbolism of the French, Africans, Indians and American Indians, the rainbow is a snake that quenches thirst in the sea..

4) Encyclopedia of Brockhaus and Efron

A rainbow is a well-known optical phenomenon in the atmosphere; observed whenthe sun illuminates the veil of falling rain and the observer is between the sun and the rain. This phenomenon is presented in the form of one, less often two concentric light arcs, drawn in the sky from the side of the falling rain and painted concentrically in a row of "rainbow" colors.ov.

5) Bible Encyclopedia

Rainbow - (arc in the cloud) - majestica natural phenomenon of nature, occurring from the refraction of light rays in raindrops. It usually happens during rain, when the sun is shining, and on the opposite side of it is a cloud from which it's raining. A rainbow is a brilliant arc-shaped band, colored by all the colors of the solar spectrum, with purple at the bottom of the arc, and red at the top.edge.

3 . The history of the study of the rainbow by scientists.

The Persian astronomer Qutb-al-Din-al-Shirazi (1236-1311), and possibly his student Kamal-al-Din-al-Farizi (1260-1320), was apparently the first to give a fairly accurate explanation of the phenomenon.

The general physical picture of the rainbow was described in 1611 by Mark Antony de Dominis in his book De radiis visus et lucis in vitris perspectivis et iride. On the basis of experimental observations, he came to the conclusion that a rainbow is obtained as a result of reflection from the inner surface of a rain drop and double refraction - when entering the drop and exiting it..

René Descartes gave a more complete explanation of the rainbow in 1635 in his Meteora, in the chapter On the Rainbow.
Although the multi-color spectrum of the rainbow is continuous, according to tradition, 7 colors are distinguished in it. It is believed that Isaac Newton was the first to choose the number 7, for which the number 7 had a special symbolic meaning. Moreover, initially he distinguished only five colors - red, yellow, green, blue and violet, which he wrote about in his Optics. But later, in an effort to create a correspondence between the number of colors of the spectrum and the number of fundamental tones of the musical scale, Newton added two more to the five listed colors of the spectrum.

In 1637 the famous French philosopher and scientist Descartes gave mathematical theory rainbow based on the refraction of light. Subsequently, this theory was supplemented by Newton on the basis of his experiments on the decomposition of light into colors using a prism. Descartes' theory, supplemented by Newton, could not explain the simultaneous existence of several rainbows, their different widths, the obligatory absence of certain colors in the color bands, the influence of the size of cloud drops on appearance phenomena. The exact theory of the rainbow based on the concept of light diffraction was given in 1836 by the English astronomer George Airy. Considering the rain veil as a spatial structure that provides the occurrence of diffraction, Airy explained all the features of the rainbow. His theory has fully retained its significance for our time.

4. Mnemonic phrases

The colors in the rainbow are arranged in a sequence corresponding to the spectrum of visible light. Exist mnemonic phrases to remember this sequence. In these phrases, the initial letter of each word corresponds to the initial letter of the name of a certain color. The colors in the phrase are listed according to the order of the colors in the rainbow, from red (longest wavelength visible light) to violet (shortest wavelength visible light).

You can get a rainbow at home with the help of such experiments.

1. A rainbow obtained by lowering a mirror into water.

Materials used: A container of water, a mirror light source (lamp, sunlight), a sheet of white cardboard.

I place a mirror in a container with water at an angle of about 25 degrees to the surface of the water. Place a sheet of white cardboard next to it. We direct the light source to the mirror, as a result of the refraction of the beam in the water and its reflection from the mirror, a rainbow appears on a sheet of cardboard.

2. Rainbow with CD.

Materials used: CD, light source (lamp, sunlight).

We direct the light source at an angle of about 25 degrees to the surface of the CD. A rainbow will appear on the surface of the CD as a result of refraction.

3. Rainbow in soap bubbles .

. Practical application of the spectrum.

Spectral analysis.

The phenomenon of dispersion is used in science and technology in the form of a method for determining the composition of a substance, called spectral analysis. This method is based on the study of light emitted or absorbed by a substance.

Spectral analysis is a method of studying chemical composition substance based on the study of its spectra.

Spectral devices are used to obtain and study spectra. The simplest spectral instruments are a prism and a diffraction grating. More accurate - spectroscope and spectrograph.

With the help of spectral analysis, it is possible to detect a given element in the composition of a complex substance, even if its mass is extremely small.

The main areas of application of spectral analysis are as follows: physical and chemical studies; mechanical engineering, metallurgy; nuclear industry; astronomy, astrophysics; criminalistics. Modern technologies for creating the latest building materials (metal-plastic, plastic) are directly interconnected with such fundamental sciences like chemistry and physics. Science data use modern methods substance research. Therefore, spectral analysis can be used to determine the chemical composition of building materials from their spectra.

7. Conclusion.

Rainbow is one of the most amazing and beautiful natural phenomena. Based on the foregoing and based on the experiments I have done, we can say that a rainbow can be reproduced at home and enjoy its beauty at any time. I also learned how the rainbow is used, or rather the decomposition of light into spectra, how important it has become in human life.

I believe that the goal of my work has been achieved, the tasks set at the beginning of the project have been fulfilled, the hypotheses have been confirmed experimentally.

Rainbow - this magnificent colorful phenomenon has long amazed the imagination of people. Looking at the rainbow, I want to believe in miracles and magic. Which of the natural phenomena can be compared with the beauty of a rainbow? The appearance of a rainbow in the sky means that soon good weather and the storm came to an end. There are many legends about the rainbow, which you will learn about from this article. We will also try to understand in more detail the reasons for the appearance of this wonderful natural phenomenon and learn about interesting facts about the rainbow. Read the article, ask questions and share your impressions in the comments.

In the ancient Indian epic "Romayana" we find the expression "seven-colored bow of Thunder". Thunderbolt - supreme god Indra, king of kings. The ancient Greeks imagined the rainbow as an intermediary between heaven and earth, that is, between gods and people. They identified the rainbow with the beautiful Irida and portrayed her dressed in silk, which intersected all seven colors. Golden wings were an indispensable attribute of Irida. They symbolized her fickle temper: after all, a rainbow always appears and disappears unexpectedly.

The Arabs believed that the rainbow is the bow of the god of light Kuzakh. After a grueling struggle with the forces of darkness, which sought to prevent the appearance of the sun in the sky, Kuzakh invariably emerged victorious and hung a rainbow bow on the clouds. Since ancient times, the Slavs considered a rainbow after heavy rain to be a messenger of victory won by the god Perun over the spirit of evil.

For a rainbow to appear, only thunder and lightning are not enough. If the sky is covered with clouds, and there is no shadow on the ground, the rainbow cannot be seen. And only when the sun breaks through the thickness of the clouds, conditions are created for its appearance. Beautiful! Changeable and elusive!

To explain the appearance of a rainbow in the sky from a theoretical point of view is not particularly difficult. This is elementary optics. How do rain and sun draw a rainbow!?

As you know, light consists of a combination of several colors: red, orange, yellow, green, blue, cyan and violet. White light passing through a prism is reflected on the other side by all the colors of the rainbow. But in order to understand what a rainbow is, you need to understand what happens inside a prism and how white light emits so many colors.

A prism is a trihedron, usually made of clear glass or plastic. A prism "draws" a mini-rainbow by decomposing complex light into a spectrum when a narrow strip of white light hits one of the triangle's faces. The scattering of light in a prism occurs due to the so-called "refractive index" of the glass. Each material has its own distinctive refractive index. When light travels through a material (such as light traveling through air and hitting a glass prism), the difference in refractive indices between air and glass causes the light to bend. The bending angle is different from the wavelength of the light. And as white light passes through the two planes of the prism, the different colors are bent (refracted) and a kind of rainbow appears. The rainbow itself is created by raindrops acting as tiny prisms. Light enters the raindrop, bounces off the other side of the raindrop, and exits. During this process, light is decomposed into a spectrum, just like it happens in a transparent trihedral prism. The angle between the incoming light beam and the outgoing light beam is 42 degrees for red and 40 degrees for violet. Due to the difference in bending angles, a rounded rim appears in the sky, i.e. rainbow. Sometimes two rainbows can appear at once. A second rainbow can form because some raindrops can immediately double-reflect. In order for two reflections to occur at the same time, drops of a certain size are needed. The main process for the appearance of a rainbow is the refraction (refraction) or "bending" of light. Light bends, or rather changes its direction, when it moves from one medium to another. A rainbow appears due to the fact that light travels at different speeds to different mediums.

So, the bend of a beam of light falls into a transparent prism. One side of the light wave is slightly slower than the other, so the beam passes through the air-glass interface at different angles (essentially the beam of light is reflected off the surface of the prism). The light turns again when it exits the prism because one side of the light is moving faster than the other. In addition to the light-bending process itself, the prism separates white light into its component colors. Each color of white light has its own characteristic frequency, which causes the colors to move at different speeds as they pass through the prism.

A color that is slowly refracted in glass bends more when it enters the prism from the air, because the color moves at different speeds in different media. A color that moves faster in the glass does not weaken much, so it does not bend as much. Due to this, all the colors of the rainbow that make up white light are separated in frequency, passing through the glass. If the glass refracts light twice, as it does in a prism, a person sees all the separated colors of white light much better. This is called scattering. Raindrops can refract and scatter light just as it does inside a prism. Under certain conditions, as a result of such refraction of light, a rainbow appears in the sky. Each drop is unique in its own way: the drop has a completely different size and consistency compared to a glass prism. When white sunlight enters a few drops of rain at a certain angle, red, orange, yellow, green, blue, indigo and violet colors appear in the sky, i.e. rainbow. Completing the rainbow are the red and violet colors of the visible light spectrum.

As light travels through the air into a drop of water, the component colors of white light begin to scatter, with the speed at which each color moves depending on their frequency. Violet color reflected in the drop is refracted at an obtuse angle, and red at a sharp angle. On the right side of the drop, some light escapes into the air, while the rest is reflected back. Some of the reflected light exits from the left side of the drop, and refraction occurs again as the light travels towards the air.

In this way, each drop scatters white sunlight into its component colors. But why do we see wide ribbons of color, as if each rainy area scatters only one specific color? This is because we only see the color that comes from each drop. When, for example, droplet A scatters white light, only one red light comes out at a certain angle, visible to our eye. Other color rays are refracted at a different angle, so we can't see them. Sunlight penetrates falling drops equally, so all nearby drops emit red light. Drop B travels slightly slower across the sky, so it can no longer emit red light. But since all other colors have a smaller wave, then drop B in this case will emit orange and all other colors of the rainbow in descending order. The last color to close the rainbow is purple with the smallest wave glow. If you look at the rainbow from above, you can see a whole circle, consisting of seven thin circles of different colors. From the ground, we can only see the arch of the rainbow appearing on the horizon. Sometimes two rainbows appear in the sky at once, one of which has a clear outline, the other looks like a blurry reflection of the first. A dim rainbow is formed according to the same principle as a clear one, however, in this case, the light is reflected from the surface inside the droplet not once, but twice. As a result of this double reflection, the light exits the drop at a different angle, so the second rainbow appears slightly higher. If you look closely, you will notice that the colors in the second rainbow are reflected in reverse order compared to the first rainbow. As a result of this refraction of light and scattering of rays, a rainbow appears. Habitual for us sunlight and water together create a new work of art, presented to us by mother nature.

Brilliant with bright, magnificent colors, the rainbow amazed the poetic imagination of primitive peoples. It either stretches above the ground, or sparkles in the very garden of Iria, where birds of paradise and winged souls rest on it.

A special, divine character was recognized behind the rainbow, as well as behind all the luminaries, therefore, just as in nature the rainbow is on the verge between a thunderstorm and sunlight, so in folk tales it is in connection with the god of thunder and lightning Perun and the bright goddess Lada, one from the names of which, by the way, Perunitsa the Thunderer. In legends, the rainbow is compared with a wide variety of objects.

Slavs since ancient times believe that the rainbow "drinks" water from lakes, rivers and seas: like a snake, lowering its sting into the water, it draws water into itself, and then releases it, which is why it rains; at the ends of the rainbow there is a cauldron with ancient gold coins. The legend draws three deities, one of which holds a rainbow and raises water from the river with it, the other creates clouds from this water, and the third, tearing them apart, causes rain. It is like a triune incarnation of Perun.

At Western Slavs there is a belief that a witch can steal a rainbow and hide it, which means producing drought on the earth.

There are also such beliefs: a rainbow is a bridge between heaven and earth; or the belt of the goddess Lada; or the path to the other world, along which the souls of the dead sometimes come to the sinful earth. This is a symbol of abundance, and if the rainbow has not appeared for a long time, one should expect hunger, crop failure.

In some places, they believed that the rainbow is a brilliant rocker, with the help of which Lada Perunitsa draws water from the sea-ocean, and then irrigates fields and fields with it. This wonderful rocker is kept in the sky, and at night - in the constellation Ursa Major. Riddles about the rainbow also retained its likening to a yoke and buckets of water: “Two seas hang on an arc”, “A multi-colored yoke hung over the river.”

Serbs, Macedonians, Bulgarians and Western Ukrainians believe that the one who passes under the rainbow changes his gender. In Western Bulgaria, they believed that “if someone wants to change his gender, he must go to the river during the rain and where the rainbow“ drinks water ”, he must drink in the same place, and then he will turn from a man into a woman and from a woman to a man". This property of the rainbow can be used to magically change the sex of the unborn child. "If a woman who had only girls was born, goes to drink water at the place where the rainbow "drinks", then after that she boys will be born.

In Bulgaria, there is also a notion that the rainbow is "the belt of the Lord, which he rinses during the rain or dries after the rain." At the same time, the rainbow is also called the "belt of samovil." Serbs and Croats say that God shows women how to weave and what colors to use with the help of a rainbow.

In ancient India, the rainbow is the bow of Indra, the god of thunder; in addition, in Hinduism and Buddhism, the "rainbow body" is the highest yogic state attainable in the realm of samsara.

In Islam, the rainbow consists of four colors - red, yellow, green and blue, corresponding to the four elements. In some African myths, a heavenly serpent is identified with a rainbow, which serves as a guardian of treasures or encircles the Earth in a ring. American Indians identify the rainbow with a staircase that leads to another world. Among the Incas, the rainbow was associated with the sacred Sun, and the Inca rulers wore its image on their coats of arms and emblems. Among the Chibcha Muisca Indians, the rainbow was considered a good deity. In the specific mountainous conditions of the Cordillera, an amazing natural phenomenon is observed: sometimes a rainbow appears against the background of a foggy haze, as if framing the multiply enlarged reflection of the observer himself. The main sanctuary dedicated to the goddess of the Rainbow, chibcha, was erected next to the mountain waterfall Tekendama, where the brightest arc is always displayed as soon as the sun's rays fall on the water spray. In Scandinavian mythology, "Bivrest" ("shaking road", "trembling path") is a rainbow-bridge connecting heaven and earth. He is guarded by the guardian of the gods Heimdall. Before the end of the world and the death of the gods, the bridge collapses. AT Ancient Greece the goddess of the rainbow was the virgin Irida, the messenger of the gods, the daughter of Taumantus and the oceanides Electra, the sister of the harpies. She was depicted with wings and a caduceus. Her attire is made up of dew drops shimmering with rainbow colors. According to the ancients, the rainbow connected heaven and earth, therefore, with the design of Olympic mythology, Irida was considered an intermediary between gods and people. Unlike Hermes, Iris carried out the orders of Zeus and Hera without showing her own initiative. The canonical image of Iris is a winged maiden (usually sitting next to Hera), holding a vessel of water in her hands, with which she delivered water to the clouds.

According to the Bible, the rainbow was created by God after the global flood, as a sign of his promise to never flood people again. In the Talmudic tradition, the rainbow was created by God on the sixth day of creation. The Greeks have a rainbow - a manifestation of the goddess Iris. In medieval Christian images, on the day of the Last Judgment, Christ is seated on a rainbow. The rainbow is also associated with the Virgin Mary, the mediator between God and people. The symbolism of the rainbow depends on the number of colors in it.
So in China, five colors are distinguished in the rainbow, the combination of which personifies the unity of yin and yang. On the basis of the Aristotelian triad, the Christian West sees in it only three (symbol of the Trinity) primary colors: blue (the heavenly nature of Christ), red (the passion of Christ) and green (the mission of Christ on earth).
A rainbow is an image of peaceful heavenly fire, in contrast to lightning as an expression of the wrath of heavenly powers. The appearance of a rainbow after a thunderstorm, against the backdrop of peaceful nature, along with the sun, made it possible to interpret it as a symbol of peace. In the Bible, the rainbow appears (in the episode with Noah's ark) as a sign that the water will no longer be a flood; in general, it is seen as a symbol of the covenant between Yahweh and people. The hemisphere of the rainbow was considered a sphere (the second half of which is supposedly submerged in the ocean), which
emphasized the divine perfection of this natural phenomenon. According to a common interpretation, the red color of the rainbow represents the wrath of God, yellow - generosity, green - hope, blue - the appeasement of natural forces, purple - greatness.

In the sky, the rainbow shines and shines,
As if the passage was open to us through it.
A multi-colored beam descended from the sky,
The forest shines in beautiful rainbow dust.

Foliage shimmers like an emerald
Reflections of the rainbow are visible here and there,
The forest plunged into a fairy tale and calmed down,
He wants to delay a wonderful moment.

Science has explained everything to us for a long time,
But to fully understand nature is not given.
Seeing a rainbow in the sky blue,
We dream that these are symbols from the outside.

Rapture takes us to sky-high flight,
Perhaps there lies the solution to a miracle.
A rainbow shines on us, fresh and good,
From bright colors eyes glow with happiness.
