Question

What is the relationship between critical angle and refractive index

Answer 1

Answer:

The relationship between critical angle and refractive index is 1/R = sin C

Explanation:

Critical angle:- The angle of incidence at which the angle of refraction is 90°.

Refractive index:- The ratio of velocity of a light ray in the air to the given medium.

So, The relationship between critical angle and refractive index is,

sin of critical angle is inversely proportional to the refractive index

1/R = sin C

where, R = refractive index

C = critical angle

It should be noted that refractive index is inversely proportional to critical angle.

Answer 2

Answer :

Refractive index =1/sinc
