Question 306: Ray Optics

Question

In total internal reflection when the angle of incidence is equal to the critical angle for the pair of media in contact, what will be angle of refraction?

Accepted Answer

Let i
c
be the critical angle.
Hence, at i = i
c
, refracted ray grazes with the surface.
So, angle of refraction is 90ÃÂ°.
