Unpolarized light passes through two polarizing filters. After passing through the first filter the intensity of the light (11) is 17 W/m2. The first filter is vertical (0 degrees), while the second filter is angled at 34 degrees. What is the new intensity of the light? If you have unpolarized light passing through two polarizing filters that are lined up to the same direction. How can you rotate them to block all light from passing through? rotate one by 45°...
