Question

what is the relationship between critical angle and refractive index ​

Answer 1

Answer:

In Optics, The angle of incidence to which the angle of refraction is 900 is called critical angle. The ratio of velocities of a light ray in the air to the given medium is refractive index.

Answer 2

Explanation:

In optics, the angle of incidence to which the angle of refraction 90 degrees called Critical Angle. the ratio of velocities of a light in the air to the given medium is refractive index .
