A parallel polarized beam of light with an electric field amplitude of 10 (V/m) is incident in air on polystyrene with μr = 1 and r = 2:6. If the incidence angle at the air–polystyrene planar boundary is 50_, determine
(a) The reflectivity and transmissivity, and
(b) The power carried by the incident, reflected, and transmitted beams if the spot on the boundary illuminated by the incident beam is 1 m2 in area.
