Initially unpolarized light is icident on a series of three polarizers, with the first axis verticle, the second axis rotated an angle (theta) with respect to the first and third rotated by an angle of (theta) with respect to the second.

a) The initial intensity is 160 W/m^2 and final transmitted intensity is 5 W/m^2. What is the angle (theta) between the neighboring polarizers?
