A narrow beam of natural light falls on a set of N thick plane-parallel glass plates at the Brewster angle. Find:
(a) the degree P of polarization of the transmitted beam;
(b) what P is equal to when N = 1, 2, 5, and 10.
*(a) When natural light is incident on a glass plate at Brewster’ angle, the transmitted light has**
where I0 is the incident intensity
After passing through the 2nd plate we find
