P.8-38 A uniform plane wave of angular frequency w in medium 1 having a refractive index n, is incident on a plane interface at z = 0 with medium 2 having a refractive index nz (<n) at the critical angle. Let E, and Eo denote the amplitudes of the incident and refracted electric field intensities, respectively. a) Find the ratio E.0/Eo for perpendicular polarization. b) Find the ratio Eo/E40 for parallel polarization. alon c) Write the instantaneous expressions of E(x, z; 1) and E/(x, z; t) for perpendicular polarization in terms of the parameters 0, n., 12, 0, and E0
