Question

State the relation between the refractive index and
critical angle.​

Answer 1

Answer:

I don't know if I could know I tell you

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.
