In Fig. 33-58, light from ray A refracts from material 1 ( n 1 = 1.60) into a thin layer of material 2 ( n 2 = 1.80), crosses that layer, and is then incident at the critical angle on the interface between materials 2 and 3 ( n 2 = 130), (a) What is the value of incident angle θ A ? (b) If θ A is decreased, does part of the light refract into material 3? Figure 33-58 Problem 60. Light from ray B refracts from material l into the thin layer, crosses that layer, and is then incident at the critical angle on the interface between materials 2 and 3. (c) What is the value of incident angle θ B ? (d) If θ B is decreased, does part of the light refract into material 3?

Plane - polarized light is incident on a single polarizing disk, with the direction of E 0 parallel to the direction of the transmission axis. Through what angle should the disk be rotated so that the intensity in the transmitted beam is reduced by a factor of (a) 2.00, (b) 4.00, and (c) 6.00?
The electric field of a harmonic plane electromagnetic wave propagating in vacuum is given by (0 , 0 , 4)cos(3x-ωt) V/m; hence the corresponding magnetic field is:
