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

Correct answer

2

Step-by-step solution

After critical angle reflection will be 100 % and transmission is 0 % . Options (b) and (c) satisfy this condition. But option (c) is the correct option. Because in option (b) transmission is given 100 % at =0^ , which is not true. Analysis of Question From examination point of view question is moderately difficult. Because it takes little time to understand the given graphs clearly.
