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

TestHub · Accepted Answer

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 θ = 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.
