WebIn order to find the polarization angle and angle of refraction, we will apply Brewster’s law: μ = tan ip. Or, ip = tan−1tan−1 (1.9128) Or, ip = 62o 24’. Now we will see that our angle of refraction: It is specified that ip + ir = 90 degrees. Thus, angle of refraction or ir = 90 – 62o 24’. Therefore, our angle of refraction comes ...
