One of the most amazing phenomena of inanimate nature is the rainbow. She always surprised and amazed with her beauty. Scientists have been pondering this mysterious effect for a long time. As everyone knows, a rainbow in nature accompanies rain, as if accompanying it. Its appearance depends on how the cloud moves, bringing precipitation. It occurs before the rain, during it, or when it is already over.
What it is?
This is a colored arc with an angular radius of 42 °, it can be seen in the background of the rain. It is found in that side of the sky, which is opposite to the sun. This despite the fact that the sun is not covered by clouds. Very often, such conditions are created in the hot season, that is, in the summer, when mushroom rains. The center of the rainbow is an antisolar point diametrically opposed to the sun. Even small children know that there are seven colors in the rainbow. And also it can be seen near fountains and waterfalls. She appears against the background of drops.
Where does this mysterious multi-colored light come from? A rainbow in nature is sunlight broken into parts, it is its source. He moves in such a way that he sees us emanating from the part of the sky that is opposite to the Sun. Features of the rainbow explains the theory of Descartes-Newton. It was created more than three hundred years ago.
That object, which lays out a ray of light into its particles, is called a prism. If it comes to the appearance of a rainbow, then drops of rain or water help her. Since they play the role of the same prism. A rainbow in nature is a huge spectrum or a strip of multicolor lines, which were formed as a result of decomposition when they passed through raindrops.
Colors
Shades are arranged in a strict order. It looks, for example, like this: "Every hunter wants to know where the pheasant sits." Very easy to remember. The first letter in each word corresponds to the name of the color on the rainbow itself:
- Red.
- Orange.
- Yellow.
- Green.
- Blue.
- Blue.
- Purple.
A rainbow in nature appears at a time when the Sun shines along with a stream of rain. To see this magnificent phenomenon, it is necessary to be between the heavenly body and, of course, precipitation. Only the Sun should be at the back, and rain should be at the front.
Rainbow as a natural phenomenon
This arc, shining with various colors, has always been of interest to primitive peoples. They came up with different stories and fables. For example, the fact that a rainbow opens over the planet, and birds from paradise and soul rest on it. And the Slavs have long believed that a rainbow drinks water from lakes, seas and rivers, as if a snake, lowering its sting, draws water and starts to rain. There is a strange belief that an evil witch will one day steal the celestial arc, and there will be a drought on the planet that will destroy all life.
Each country has its own beliefs that tell about national heroes. For example, the Arabs believed that the rainbow is the bow of the god Kuzakh. And after a hard battle with dark forces that did not want the Sun to shine in the sky, he hung his weapon on the clouds. Or that the rainbow is the line between the earth and the sky. And the souls who lived in the sky descend on it, visiting our planet. Croats believe that God teaches women to combine colors correctly with a rainbow, as it contains seven primary colors.
