What is the Rainbow, its colors, everything that is associated with the multicolored arc in the sky

There is no person on earth who does not admire the appearance in the sky after the rain with the breathtaking beauty of the colorful arc - the Rainbow. What is this, how is this wonderful phenomenon of Nature formed?

The mystery of the origin of the rainbow has always fascinated and captivated the spirit. In the distant past, people tried to explain the appearance of a multicolored arc in the sky with the help of myths and legends.

Today we will talk about what a rainbow is and how it is formed.

Legends and Myths about the Rainbow

Everyone knows that ancient people were apt to deify and mystify most natural phenomena, whetherthen thunder and lightning or an earthquake. They did not avoid the rainbow. What do we know from our ancestors? What is a rainbow and how does it work?

1. The ancient Vikings believed that the rainbow is the bridge Bivrest, connecting the land of the people of Mitgard and the gods( Asgard).
2. Indians believed that the rainbow is a bow belonging to the god of thunder Indra.
3. The Greeks did not go far from their contemporaries and also considered the rainbow of the dear messenger of the gods of Irida.
4. Armenians decided that this is not a natural phenomenon, but the belt of the Sun God( but, having not decided, they changed the "specialty" to God and "forced" him to be responsible for art and science).
5. Australians went further and animated the rainbow, making it a serpent-patron of water.
6. On African myths, where the rainbow touches the ground, you can find a treasure.
7. It's interesting what Africans and Irish have in common, because their Leprechaun also hides a pot of gold at the end of the rainbow.

You can still enumerate the myths and legends of peoples from all over the world, and we each would find something interesting. But what is a rainbow really?

History of the

study The first realized and close to reality conclusions on the observed atmospheric phenomenon was given by Aristotle. It was just a guess, but he was the first person to translate the rainbow from the section of myths into the real world.

Aristotle hypothesized that a rainbow is not an object or substance, and not even a real object, but simply a visual effect, an image that is akin to a mirage in the desert.

However, the first scientific study and justification was conducted by the Arab astronomer Qutb ad-Din al-Shirazi. At the same time, similar studies were carried out by German researchers.

In 1611, the first physical theory of rainbow justification was created. Mark Antony de Dominies, on the basis of observations and experiments, came to the conclusion that a rainbow is formed due to the refraction of light in drops of water contained in the atmosphere in rainy weather.

To be more precise, he described the full picture of the occurrence of a rainbow due to the double refraction of light at the entrance and exit from a drop of water.

Physics

Probably everyone has heard about the existence of infrared and ultraviolet radiation? This "light", which comes from any material objects in different ranges of measurement.

So, sunlight consists of rays with different wavelengths and includes all kinds of radiation from "warm" red to "cold" violet. When passing through water droplets, the light is divided into rays with different wavelengths( and different colors), and this happens twice, when it hits the water, the beam splits and deviates slightly from its path, and when the output deviates even more, the rainbow can be seenwith the naked eye.

For children

Of course, anyone will tell you about the rainbow, even though he finished the school at least three. But what if the child approaches the parent and asks: "Mom, what is a rainbow?"Where does it come from? ".The easiest way to explain this is: "It's the sun's rays, passing through the rain, pouring out."At a younger age, children do not need to know the physical background of the phenomenon.

All known colors of the rainbow are of strict order and always the same sequence. As we have already explained, this is the result of physical processes. However, for some reason, many adults( parents, caretakers in kindergartens) require children to know the correct order of the flowers in the rainbow. For faster memorization, expressions were invented in which the first letters of the words symbolize a certain color.

Here are the most famous forms:

Every Hunter Wants to Know Where Pheasant Sits.

Every Designer Wishes To Know Where To Download Photoshop.

As you can see, you can track the correct order of the arrangement of colors on the first letter( red-orange-yellow-green-blue-blue-violet).By the way, Isaac Newton distinguished not blue and blue colors, but blue and indigo, respectively.

Why the names of colors have been changed, remains a mystery. But in general, is it really so important to know what a rainbow is, in order to admire it?
