A light ray traveling in glass medium is incident on glass-air interface at an angle of incidence `theta`. The reflected ® and transmitted (T) intensities. Both as reflected 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 `thetagti_(c)` , all the light rays will be total internal reflrcted. So transmitted intensity `=0`
So correct answer is `(C)`
