Q. A light ray travelling in glass medium is incident on 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

IIT JEEIIT JEE 2011

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 $\theta$ = 0$^{\circ}$, which is not true.
$\therefore $ The correct answer is (c).
