Question

describe the snell's law snell's law​

Answer 1

Here is your answer,

The ratio of sine of angle of incidence to sine of angle of refraction for a pair of medium is constant. This law is also known as Snell's law.

sin i /sin r = constant

                 = a with respect to g

                 = refractive index of glass with respect to air.

Answer 2

Snell's law :-

1st law :-

$\frac{ \sin(i) }{ \sin(r) } = constant$

2nd law :-The refracted,normal rays will lies on the point of incidence on the same plane

What is light ?

Light is a form of energy.It makes us to see objects around us.It is independent medium

What is refraction of light ?

The phenomenon due which the rays deviate from their path,while travelling from one optical medium to another optical medium,is called as refraction of light
