Unpolarized light with I=120 w/m^2 travels in the x direction and passes through a linearly polarizing film oriented in the z direction, and then another linearly polarizing film oriented in the y direction.
A) What is the intensity of the beam after passing through the first film?
B) what is the intensity of the beam after passing through the second film?
C) Suppose I place a third film between the other two, oriented 30 degrees with respect to the z direction. What is the final intensity of the beam passing through all three polarizing films?
