plz answer fast it's urgent

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

Heya Friend

Rainbow is form by the process of internal reflection in the raindrop.

Rainbow is a spectrum.

The water droplets are present in atmosphere after the rain .

Actually , Rainbow is formed by dispersion of sunlight by tiny water droplets in atmosphere.

The water droplets acts as a prism , and I think thik you know the process of dispersion of light through prism.

When we see a rainbow we can find that it is formed to the opposite direction of sun.

The water droplets refracts and disperses the sunlight which is incident on the water droplets, then reflects the light internally, and finally it refracts it again when it comes out of the rain drops .

This process happens in millions of raindrops or water droplets.

This causes seven colours to get into atmosphere , which form a rainbow for the observer's eye .
