33. (a) Since the incident light is unpolarized, half the intensity is transmitted and half is absorbed. Thus the transmitted intensity is I =5 . 0mW / m 2 . The intensity and the electric Feld amplitude are related by I = E 2 m / 2 µ 0 c ,so E m = p 2 µ 0 cI = q 2(4 π × 10 7 H / m)(3 . 00 × 10 8 m
