Polarization

Text

The animation shows an E&M wave propagating in the z direction and passing through two polarizers.  The gray square represents the polarizer and the black line represents the direction of polarization. The magnetic field is not shown.  You may click-drag in the animation to change the viewing angle.  What fraction of the energy passes through the second polarizer?   Start

Hint

What is the angle of the polarizer with respect to the incident  wave's polarization? 

Answer

0.25.
