A light ray travelling in glass medium is incident of glass- air interface at an angle of incidence `theta`. The reflected `(R )` and transmitted (T) intensities, both as function of `theta`, are plotted The correct sketch is

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
c
Initially, most of part will be transmitted. When `theta gt i_(c)`. All the light rays will be total internal reflected. So transmitted intensity = 0.
