In the ray diagram of Fig. 33-63, where the angles are not drawn to scale, the ray is incident at the critical angle on the interface between materials 2 and 3.Angle f 60.0, and two of the indexes of refraction are n1 1.70 and n2 1.60. Find (a) index of refraction n3 and (b) angle u. (c) If u is decreased, does light refract into material 3? n2n3n1 Figure 33-63 67.
