Light of original intensity l₀passes through two ideal polarizing filters having their polarizing axes oriented as shown in Fig. E33.32. You want to adjust the angle Ï• so that the intensity at point P is equal to l₀/10.

(a) If the original light is unpolarized, what should Ï• be?

(b) If the original light is linearly polarized in the same direction as the polarizing axis of the first polarizer the light reaches, what should Ï• be?
