Solution Summary

The pointing vector of a given EM wave which is polarized in the plane of incidence is given.

Solution Preview

Intensity, I = 50 W/m^2

1. Because,
I = (1/2)*epsilon_o * Eo^2 * c

epsilon_o = Permittivity of free space = 8.86*10^(-12) C^2/N.m^2

c = speed of light = 3*10^8 m/s

Hence,

50 = ...
