1. Unpolarized light falls on two polarizing filters placed one on the top of the other. What must be the angle between the polarizeng directions of the filters if the intensity of the transmitted light is (a) one-third the maximum intensity of the transmitted beam or (b) one-third the intensity of the incident beam? 2. When a beam of parallel unpolarized light is incident on the surface of a plane glass at an angle 58, the reflected light is completely polarized. Find (a) the refraction angle of refraction light; (b) the refractive index of the glass.
