A long solid cylindrical glass rod of refractive index 3/2 is immersed in a liquid of refractive index `(3sqrt(3))/(4)`. The ends of the rod are perpendicular to the central axis of the rod. A light enters one end of the rod at the central axis as shown in the figure . find the maximum value of angle `theta` for which total internal reflection occurs inside the rod?
