Question

A light ray travels from glass to air at an angle of incidence ?? = 35 . The ray partially reflected from the glass-air boundary at the angle ?? and partially refracted at the angle ??. The index of refraction of the glass is 1.6 a) What is the angle of reflection ??? b) What is angle of refraction ??? c) What is the minimum value of ?? at which light doesn’t emerge from the top face of the glass?
