The refractive indices of medium A and B are nA
and nB respectively. Total internal reflection
is possible on going form which medium to which medium given that nA > nB
.

maria9 Total internal refraction occurs when light travells from optically denser medium to lighter medium.

optical density is directly proportional to refractive index.

here nA > nB

therefore optical density of A is more than B

so light travells from A to B
