In the figure, a light ray is incident at angle 0 = 53° on a series of five transparent layers with parallel boundaries. For layers 1 and 3, L1 = 29 µm, L3 = 39 um, n1 = 1.7, and ng = 1.60. (a) At what angle does the light emerge back into air at the right? (b) How much time does the light take to travel through layer 3? Air ng Air (a) Number 53 Units * (degrees) (b) Number 24016 Units ns
