Chapter 33, Problem 83P

SSM A ray of white light traveling through fused quartz is incident at a quartz–air interface at angle θ₁. Assume that the index of refraction of quartz is n = 1.456 at the red end of the visible range and n = 1.470 at the blue end. If θ₁, is (a) 42.00°, (b) 43.10°, and (c) 44.00°. is the refracted light white, white dominated by the red end of the visible range, or while dominated by the blue end of the visible range, or is there no refracted light?
