										Dear kaushik
The critical angle is the angle of incidence above which total internal reflection occurs. The angle of incidence is measured with respect to the normal at the refractive boundary. The critical angle θc is given by:
$\theta_c = \arcsin \left( \frac{n_2}{n_1} \right),$critical angle = arcsin(4/3 / 3/2) = 62.73 degresPlease                 feel free to post as many doubts on our   discussion   forum   as     you       can.we   will get you the answer and   detailed      solution   very      quickly.
