Extracted text: Exercise 8.4 A parallel-polarized beam of light with an electric field amplitude of 10 (V/m) is incident in air on polystyrene with Hr = 1 and &r = 2.6. If the incidence angle at the air-polystyrene planar boundary is 50 , determine the following: (a) The reflectivity and transmissivity. (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.
