Question

with the help of ray diagram state the meaning of refraction of light State Law of refraction of light and also Express it mathematically​

Answer 1

The Refraction of light

The change in the speed of light ray,as

travel from one medium to another medium

or we can simply say bending of light ray

Laws of Refraction

I) The incident,reflected,normal ray at the interface of two transparent medium lies on the same base.

ii) The ratio of incident to ratio of reflection is constant form given pair of media and color

(snell's law)

sin i/sin r = constant
