The drawing shows a ray of light travelling through three materials whose surfaces are parallel to each other. The refracted rays (but not the reflected rays) are shown as the light passes through each material. A ray of light strikes the a-b interface at a 50.0o angle of incidence. The index of reflection of materials a is na = 1.20. The angles of refraction in materials b and c are respectively, 39.0o and 53.9o. Find the indices of refraction in these two media.
