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 `thetagti_(c)` , all the light rays will be total internal reflrcted. So transmitted intensity `=0`
So correct answer is `(C)`
