Practice Problem on Polarizers
incoming at 130 deg. 170 deg. 60 deg. 140 deg.
130o 170o 60o 140o

Polarized light at angle 130 degrees of intensity I0 is incident from the left and passes sequentially through polarizers at angles 170, 60, and 140 degrees an indicated above. What is the intensity and polarization of the light exiting on the right? Give your answer in terms of I0 to three decimal places. (Angles are measured from the vertical going counterclockwise.)

ANSWER = 0.002 I0 at 140 degrees
