A system of three polarizers P

_{1}, P_{2}, P_{3}is set up such that the pass axis of P_{3}is crossed with respect to that of P_{1}. The pass axis of P_{2}is inclined at 60^{o}to the pass axis of P_{3}. When a beam of unpolarized light of intensity I0 is incident on P_{1}, the intensity of light transmitted by the three polarizers is I. The ratio ($${{{I_0}} \over I}$$) equals (nearly) :2
