When the Throne stops, the clouds dissipate and the Sun brings out its shining spider, sometimes a colorful bow becomes in the sky right in front of it. It is called Rainbow or Dhank. It is visible only during the day. Not at night, because it is made of sunlight.
Sunlight appears to be white on the surface, but in reality it has rays of different colors, which are not visible due to their confusion. When these rays pass through glass or water, they become crooked and separate. And we can see their colors separately. To understand this better, take a manifesto. It is a triangular piece of special glass. Rotate this manifesto slowly towards the sun.
You will see many colors inside it. Now go to a dark room and open the window so that a small ray of sun can come in through it. Place a table in front of this ray and slowly rotate the white paper, the manifesto in front of the light on the table. This is exactly how the sky falls. After the rain stops, tiny droplets of water remain in the air.
When the sun's rays pass through these particles, they become crooked and separate and we see their different colors in the form of a bow. But this spectacle lasts for a while. As soon as the particles disappear, the rays intersect. Get confused.
And the color bow disappears. In order for the sun to set, it is necessary for the sun to be in the east or in the west. That is, the rays of the sun should fall diagonally on the drops of water. So to the east.
I adore the rainbow and I am preparing an article in which it says where the rainbow appears according to the belief of one nation.
