Light is directed on the surface of the non-conductive material at an angle of incidence of pi/6, just outside of this surface the intensity is 50(W/M^2). The EM wave is polarized in the plane of incidence.© BrainMass Inc. brainmass.com October 10, 2019, 7:14 am ad1c9bdddf
Intensity, I = 50 W/m^2
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
50 = ...
The pointing vector of a given EM wave which is polarized in the plane of incidence is given.
