A beam of light propagating in medium A with index of refraction n ( A ) passes across an interface into medium B with index of refraction n ( B ). The angle of incidence is greater than the angle of refraction, v ( A ) and v ( B ) denotes the speed of light in A and B . Then which of the following is true
