Question

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.

Answer 1

Correct Answer - C
When angle of incidence `(theta)` is less than critical angle `(theta_( c))`, there will be partial transmission and partial reflection of light in a glass medium. When `theta gt theta_( c)`, there will be `100%` reflection of light. In this situation, the transmitted intensity if light is zero. Choice ( c) is correct.
