Example 7.1: Unpolarized light of intensity I is made to pass through three polarizers P, P, and P, successively. The polarization axis of P, makes an angle of 0, with that of P, while that of P, makes an angle 0, with that of the P. What will be the intensity of\fExample 7.2: For what angle of incidence will light incident on a bucket filled with liquid having refractive index 1.5 be completely polarized after reflection
