B:53) 8.2 A plane wave traveling in medium 1 with e,1 = 2.25 isnormally incident upon medium 2 with e,2 = 4. Both media aremade of nonmagnetic, nonconducting materials. If the electricfield of the incident wave is given byE' = ŷ8 cos(67 × 10°t – 307x)(V/m).(a) Obtain time-domain expressions for the electric andmagnetic fields in each of the two media.(b) Determine the average power densities of the incident,reflected, and transmitted waves.
