A wide slab consisting of two media of refractive indices n1 an n2 is placed in air as shown in the figure. A ray of light is incident from medium n1 to n2 at an angle theta, where sin(theta) is slightly larger than 1/n1. Take refractive index of air as 1. Which of the following statement(s) is (area) correct?
A) The light ray enters air if n2-n1
B) The light ray is finally refractive index n1 is n2 is less than n1.
C) The light ray is finally reflected back into the medium of refractive index n1 if n2 greater than n1.
D) The light ray is reflected back into the medium of refractive index n1 if n2=1.
