What is the relation between the refractive indices mu,mu_(1) and mu_(2) if the behaviour of light rays is shown in Figure.

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.
