A wide slab consisting of two media of refractive indices n and n is placed in air as shown in the figure. A ray of light is incident from medium n to n at an angle 0, where sin 0 is slightly larger than 1/n. Take refractive index of air as 1. Which of the following statement(s) is(are) correct? air ******** 1 n (A) The light ray enters air if n = n (B) The light ray is finally reflected back into the medium of refractive index n if n n (D) The light ray is reflected back into the medium of refractive index n if n = 1 A wide slab consisting of two media of refractive indices n and n is placed in air as shown in the figure.
