Question

A ray of light is incident on the
Surface of transparent medium at an angle of 45° and is refracted in the medium at an angle of 30° what will be the velocity of light in the transparent medium? ​

Answer 1

Answer:

2.14×10^8

Explanation:

n=sin i/sin r

n=0.707/0.5

n=1.401

also n=v of medium 1/v of medium 2

n=3×10^8/v of medium 2

1.401=3×10^8/V2

1.401V2=3×10^8

V2=3×10^8/1.401

V2=2.14×10^8
