Question

What is the reason for
formation of rainbow?​

Answer 1

Explanation:

rainbow is caused by sunlight and atmospheric conditions. Light enters a water droplet, slowing down and bending as it goes from air to denser water. The light reflects off the inside of the droplet, separating into its component wavelengths--or colors. When light exits the droplet, it makes a rainbow.

Answer 2

Rainbows are formed when light shines through water, like when the sun shines through the rain. This light is bent and reflected, like a reflection in a mirror, and this causes all of the amazing colors that you see.
