A ray of one color for which n= 1.53 and a Ray of another color, for which n= 1.58 travel through a piece of glass. They meet right at the boundary between the glass and the air and emerge into the air as one ray with an angle of refraction of 20.74 degree. What is the angle between the two rays in the glass? Give the answer in degrees.
