Unpolarized light passes through three polarizing filters. the first one is oriented with a horizontal transmission axis, the second filter has its transmission axis 31.8° from the horizontal, and the third one has a vertical transmission axis. what percent of the light gets through this combination of filters?

10.028%

Explanation:

= Angle between polarizer

The polarized light after passing through first polarizer

The polarized light after passing through second polarizer

The polarized light after passing through third polarizer

The percent of the light gets through this combination of filters is 10.028%

wavelength divides in half and speed stays the same.
