If the index of refraction for a certain glass is 1.5, and the angle of refraction is 15 degrees for a ray of light traveling from air (index of 1) what is the angle of incidence? (in coming beam)
Round your answer to the nearest tenth of a digit. The answer is in degrees so don't worry about the units
