Light rays that “bounce off ” a surface are reflected by the surface. If the surface is partially transparent, some of the light rays are bent or refracted as they pass from the air through the material. The angles of reflection θ1 and of refraction θ2 in the diagram at the right are related by the equation sin θ1 = n sin θ2. If θ1 = 60° and n = √3, find the measure of θ2
