(1). A ray of light strikes a thick sheet of glass (n = 1.5) at an angle of 25 with the normal. Find the angle of the refracted ray within the glass with respect to the normal. (2). A light ray in air is incident on an air-to-glass boundary at an angle of 30.0° and is refracted in the glass at an angle of 21.0 with the normal. Find the index of refraction of the glass.

Question: If a beam of light is incident from water (n = 1.33) to crown glass (n1.52) with an incident angle of 40.0 degrees, what is the angle of the refracted beam of light?
