A monochromatic light is incident on the plane interface AB between two media of refractive indices mu_(1) and (mu_(2)gtmu_(1)) at an angle of incidence theta as shown in Fig. The angle theta is infinitesimally greater than the critical angle for the two media so that total internal reflection takes place. Now, if a transparent slab DEFG of uniform thickness and of refractive index mu_(3) is introduced on the interface (as shown in the figure), show that for any value of mu_(3) all light will ultimately be reflected back into medium II.

A ray of light, travelling in a medium of refractive index 'mu_, is incident at an angle i on a composite transparent plate consisting of three plates of refractive indices mu_1,mu_2 and mu_3. The ray emerges from the composite plate into a medium of refractive index mu_4, at angle x. Then,
