rainbow 

Sometimes when the sun rises after rain, the sky becomes an arc of attractive and beautiful colors. Scientists say that it is made not in one or two but in 12 different ways. According to Jean-Richard, an expert at the French Meteorological Research Center. After that, in two or three pairs, the "rainbow" gets wet. Some of them change color after a time.

Sometimes this change happens within minutes. In the process of forming a rainbow or thunderstorm, the sun's rays are reflected and refracted by water droplets, which split the light into seven colors and one half of each of the seven colors. A circle is formed. But because of the different wavelengths of light, different colors change in different ways.

They also have four and five color shades. They are called RB One, RB Two and RB Three. According to experts, the total number of flavors of Dhanak is 12. For example, in the four types of Dhanak, all colors are visible, while in RB-6 green color is not found. Similarly, only blue and red are dominant in RB-9.

According to experts, rainbow is actually a manifestation of nature, in which water droplets in the atmosphere after rainfall act like a triangle and when the sun's rays pass through them, they are divided into seven colors. A storm appears in the sky. A rainbow appears when raindrops are present in the atmosphere and sunlight is reflected from a small angle behind the observer. But there may be clouds there and half the sky is clear. There is a high probability of flooding around the fountain.

The colors of Dhanak include red, orange, yellow, green, blue, violet and dark blue. After entering the water drop, the sun's rays bend and return to the end of the drop, get reflected and bend back. Then, coming out of the drop, they twist again. Experts say that a rainbow or thunderstorm does not actually exist in the sky, but is an optical phenomenon, the location of which depends on the location of the observer. All water droplets bend and reflect the sun's rays, but only a few drops of light reach the viewer.

According to experts, the minimum height of rain clouds is 1200 meters. If anything equal to the weight and size of a drop of rain water fell from such a height, it would hit the earth at a speed of 558 kilometers per hour. Of course, anything falling at such a high speed would do a lot of damage as soon as it hits the ground. If it rains like this, then all the agricultural land will be destroyed. Residential areas, houses and motor vehicles will be destroyed. This is due to their special structure. This special structure of these droplets increases the effect of atmospheric friction and when that drop reaches a certain speed, its specific structure does not allow its speed to increase further.

Furthermore, these data relate to clouds at an altitude of 1,200 m, while also rain clouds at an altitude of 10,000 m above ground. The speed of a rain drop falling from this height is very destructive. What would happen but it doesn't happen. The average speed of raindrops (when they reach the ground) is eight to ten kilometers per hour.


Rain has been a miracle for people for a long time. It was only after the invention of air radar that it became possible to understand the phases of rainfall. The process of precipitation is not completed in one but in several stages. First, the "raw material" (rainwater), that is, water, needed for rain, reaches the atmosphere, then clouds form, and finally raindrops come into existence. These droplets later cause rainbows. ,
