Question

how is rainbow formed?

Answer 1

A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun.

Answer 2

Explanation:

A rainbow is formed due to the dispersion of light. Just after the rainfall, there are a large number of water droplets suspended in the atmosphere. these droplets act like tiny prisms, when the sunlight passes through the spherical droplets it undergoes dispersion. With a large number of water droplets contributing to this phenomenon we get to see a huge continuous band of seven colours displayed in the sky.
