Light traveling trhought three transparent substances follows the path shown in figure. Arrange the indices of refraction in order from smallest to largest. Not the total internal reflection does occur on the bottom surface of medium 2.

For total internal reflection to take place, the angle of incidence i and the refractive index mu of the medium must satisfy the inequality

Monochramatic light is incident on the pLane interface AB between two media of refractive indices mu_1 and mu_2(mu_2gtmu_1) at an angle of incidence theta as shown in figure. The angle theta is infinitesimally greater thannte critical angle for the two media so thast total internal reflection takes place. Now, if a transparent slab DEFG of uniform thickness and of refractive inde mu_2 is introduced on theinterface (as shown in figure ) , show that for any value of mu_2 all light will ultimately be reflected back into medium II.
