The light from an ordinary flashlight is passed through a vertical linear polarizer with its transmission axis vertical. The resulting beam, having an irradiance of 150 W/m2, is incident normally on a second vertical linear polarizer whose transmission axis is tilted at 35° above the horizontal.

How much light is transmitted through the second polarizer? W/m2

What is the final polarization state?
Vertical - alligned with the first polarizer.
Alligned with the second polarizer.
Unpolarized, since the flashlight beam is unpolarized.
