Question

Light enters at an angle of incidence in a
transparent rod of refractive index n. For what
value of the refractive index of the material of the
rod the light once entered into it will not leave it
through its lateral face whatsoever be the value
of angle of incidence?
(a) n > √2 (b) n = 1
