The drawing shows three materials, a, b, and c. A ray of light strikes the a-b interface at an angle that just barely exceeds its critical angle of 40.0°. The reflected ray then strikes the a-c interface at an angle of incidence that just barely exceeds its critical angle (which is not 40.0°). The index of refraction of material a is na = 1.80. Find the indices of refraction for the two other materials.
