Light of original intensity I0 passes through two idealpolarizing filters having their polarizing axes oriented as shownin the figure (Figure 1). You want to adjust the angle Ï• so thatthe intensity at point P is equal to I0/8.00.
A.)If the original light is unpolarized, what should Ï•be?
B.)If the original light is linearly polarized in the samedirection as the polarizing axis of the first polarizer the lightreaches, what should Ï• be?
