Required information
An unpolarized beam of light (intensity (0) is moving in the x-direction.
The light passes through three ideal polarizers whose transmission
axes are (in order) at angles 0.0°, 53.0°, and 30.0° counterclockwise
from the y-axis in the yz-plane.
If the polarizer in the middle is removed, what is the intensity and polarization of the
light transmitted by the last polarizer?
