Question

Explain the formation of rainbow briefly?

Answer 1

HEY MATE....✌

HERE IS YOUR ANSWER :-


FORMATION OF RAINBOW :-
========================

When a light passes through a rain drop then it goes refraction and then reflection. After getting reflection it undergoes total internal reflection. After it again refraction and came out of the rain drop by splitting white light into seven colours namely;

Violet

Indigo

Blue

Green

Yellow

Orange and

Red.

When these colors reaches the eye of observer or man he/she saw a rainbow. This is the formation of Rainbow.

====================================

Answer 2

Water droplet acts as a prism. When a light or sunlight passes through the rain drop or water droplet then it undergoes refraction then dispersion. After dispersion it undergoes to Total internal reflection. And again refraction. Then it comes out of the water droplet or rain drop as a dispersion means came out as splitting into seven colours i.e.

Violet, Indigo, Blue, Green, Yellow, Orange and Red. (VIBGYOR)

These colors reach the eyes of the observer and he/she can easily saw the rainbow...
