How Are Rainbows Formed?

A rainbow is formed in the sky soon after rain. In the rainy season, we see a rainbow. A rainbow is an arc which has multicolours. ‘Arc’ means a part of the circle.

We can see a semicircle rainbow on the ground, but if we look at it from an aeroplane, we can see it in a complete circle.

In the rainy season, water drops break the Sun’s light into seven colours, and that’s why we see the rainbow in the sky when the rain and the Sun co-occur.
