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 = 1.71. find the indices of refraction for the two other materials. nb = ?
nc = ?
