Question

The refractive index of a medium ' x ' with respect to ' y ' is 2/3 and the refractive index of the medium ' y ' with respect to medium ' z ' is 4/3 . Calculate the speed of light in medium y if speed of light in medium x is 3x108 m/s *

The principle of reversibility presupposes that the attenuation of a light ray during its passage through an optical medium because of reflection, refraction, and absorption is not affected by a reversal of the direction of the ray.
