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°...

M ReviewI Constants Unpolarized light of intensity 1 W/m2 passes through a vertical polarizing fiter. The light then passes through a second polarizer whose axis 63° from the vertical. The light then passes through a third polarizer whose axis is horizontal. (Figure 1) Figure < 1of1 Unpolarized light 米 < 9of10 Part A What is the intensity of the transmitted light after passing through the horizontal polarizer? Assume that the polarizers are close enough to each other that the light's...
