Polarized light at angle 140 degrees of intensity I0 is incident from the left and passes sequentially through polarizers at angles 160, 0, and 0 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 = 0.780 I0 at 0 degrees
