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?

A

`180^@`

B

`0^@`

C

Equal to angle of incidence

D

`90^@`

Text Solution

Verified by Experts

The correct Answer is:
D

At `i=i`, refracted ray grazes with so angle of refraction is `90^@`
