Question

write the relation between critical and refractive index of the medium​

Answer 1

Answer:

Hello ❤️

$\sin \: c = \frac{1}{n}$

Where....

c is the critical angle and n is the refractive index.

Answer 2

Answer:

Relation Between Critical Angle And Refractive Index. 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.
