Unpolarized light passes through three polarizing filters. The first filter has its transmission axis parallel to the z direction, the second has its transmission axis at an angle of 30.0° from the z direction, and the third has its transmission axis at an angle of 60.0° from the z direction. If the light that emerges from the third filter has an intensity of 587.0 W/m², what is the original intensity of the light? (Assume both angles are measured in the same direction from the +z axis.)

A wave is passing through two polarizers. It is an unpolarized electromagnetic wave, and it initially has a max electric field magnitude of 20000N/C. The 1st polarizer, polarizes at an angle of 20 degrees vertical. The 2nd polarizer, polarizes at an angle of 30 degrees horizontal. What would be the intensity of a light wave that passes through the two polarizers?
