Unpolarized light is incident on a polaroid of refractive index 1.2. What should be the angle of incidence such that the reflected and refracted rays are perpendicular to each other?
Unpolarized light is incident on a polaroid of refractive index 1.2. What should be the angle of incidence such that the reflected and refracted rays are perpendicular to each other? Correct Answer 50.19°
Using Brewster’s Law, μ = tanip In this case, i + r is equal to μ/2. For glass, μ = 1.2 Therefore, ip = tan-1μ = 50.19°.
