But any observer can find similar features of the phenomenon. First, it is always a piece of the arc. In the best case-half of the ring, each tip of which rests on the ground. Sometimes you can see only a piece of the arc. It depends on the observer position. The ancient people worshiped this phenomenon, considered him a special “sign”.

They even say that it is a sign of forthcoming good luck. The rainbow is compared with the “heavenly yoke" of the bridge, gates, and so on. It occurs "nowhere" on what is not supported. Cannot touch it, only to watch enthusiastically. Its value is interpreted unambiguously only in a positive sense. None of the people on Earth believed that beauty as something sinful or bad sign. What can be said about the study of this phenomenon.

History

The Church has not welcomed the attempts of scientists to understand the processes of formation of the rainbow. She insisted that the Lord creates all physical phenomena in nature. Examples of this can be found in the history of the XVII century. So, the scientist of Dominis, who tried to carry out such studies, was excommunicated and placed under arrest. Sentence of the Inquisition, he did not wait, and died in jail. However, his body was burned (so did the heretics). The same fate expected and other inquisitive explorers. Although the thinking is they were generally correct. Obviously, arguing about how looks like a rainbow, why, they had to get to the main optical laws. Insights managed to make the scientist Czech Brand Marca.

physical phenomena in nature examples

Nature of the white light

So it happens that the person examines one small phenomenon, and obtains insights that would later be called fundamental. That is with a little experiment can begin a revolution in science. The now famous Czechs were interested in physical phenomena in nature, examples of which he saw in everyday life. Only it didn't accept the explanation of the Church about the divinity of their origin. He conducted simple experiments with sunlight. Namely considered rays passing through a faceted glass. One day, perhaps accidentally, in his hand was a piece vaguely reminiscent of a prism. He missed her through the thin beam in a dark room. The surprise was not the limit. A piece of glass entered one beam, and left as many as five, and colorful! So has been proved experimentally the complicated structure of the white light. Later it was theorized Newton.

What happens in a prism and how it relates to the appearance of a rainbow?

When a ray of white light enters a different medium, it refracts. As it consists of different waves, each of them behaves in its own way. When passing through a flat surface that cannot be seen. But in a prism, resembling a pyramid, the white light is decomposed into a spectrum. That is, the wave of a certain color is refracted differently. The output is no longer the white beam and rainbow stripe. Now remember that the phenomenon being studied appears in the rain. The sun's rays pass through the droplets, each of which resembles a prism and separated into a spectrum. And the viewer sees a rainbow in the sky. It seems that drew her in the air. The magic of this phenomenon are unlikely to disappear, even if you completely understand the mechanism of its occurrence.

What colors are in the rainbow?

Not all perceive this phenomenon in the same way. It depends on the specific conditions, even the features of the retina of the human eye. But this does not mean that rainbows appear different. No, they are all the same, it's just that sometimes certain colors are less noticeable. Sometimes the phenomenon looks pale, and sometimes – very bright. After reviewing the theory, it is possible to say with certainty which colors in the rainbow should be. First comes red. Behind him appears orange. They can merge into one lane for a person with a low sensitivity of the retina. Then appear yellow and green. Then – blue blue. They can also be perceived with one strip of the arc. It ends with purple. This “perfect” the rainbow is a rare manifestation. Except in laboratory conditions. There is even a poem for children, which is characterized by the colors of the rainbow. Here it is: “Every hunter wishes to know where sits pheasant”. The first letters of words similar to the name of the color constituting this magnificent phenomenon of nature.

Can we see the rainbow without rain?

If you understand how it is formed, the question seems very strange. In orderit made a rainbow, we need two conditions: sunlight and drops of water sprayed in the air (on the surface of plants). When does that happen? Beautiful rainbow (photo) can be formed in the waterfall or jets of the fountain. In this case, all conditions are met. It is important to note that to see a rainbow when the observer is between the water “suspension” and the sun. So, if possible, on a fine day take a walk around the fountain. You will definitely find this perspective when in the air there is a great phenomenon. It sometimes occurs in strong surf, when the waves break up into many splashes. If the sun shines brightly, you can see multicolored streaks in the air.

main natural phenomena

View from heaven

We Must understand that major natural phenomena have their own laws. Speaking of rainbows, they are quite studied. So, people wanted to know why she looks like a piece of a circle? It turns out that it depends on the point from which to observe. The sun's rays are refracted, into the human eye. They are all straight. If you draw them on a sheet of paper, we get exactly the arc. And if you look at it from above, then it will look a rainbow ring. Rarely you can see a few ‘sky bridge’. They occur when sunlight is refracted not once in the drops. Described cases of the appearance in the sky of two, three and five rainbows. A magnificent sight!

a natural phenomenon of the summer

A Different perception of the rainbow

Scientific substantiation of the phenomena boring. It is incomparable with the sensations experienced by the viewer. Sometimes even sorry that all this is fully explained by science. Natural phenomenon of the summer, including this "sign heaven”, fill viewers with a feeling of incredible joy, extraordinary miracle. It is even described in Scripture. It was a sign from the Lord the suffering of the righteous. When Noah, escaping the flood, swam in the turbulent waters without hope, but with a deep belief in the soul, he was granted a sign. It was the rainbow that appeared in the sky after a rainstorm that lasted forty days. Noah realized that saved. With the time, the colorful arc is considered a good omen, a sign from God. They say she only appears good, righteous people. Do you see the rainbow?
