Light reflected from a horizontal surface, such as a road or a lake, has a partial horizontal polarization. We can think of the light as a mixture of horizontally polarized light and unpolarized light. Suppose the reflected light from a road surface is 50% polarized and 50% unpolarized. The light intensity is 120 W/m² What is the intensity after the light passes through a polarizing filter whose axis makes an angle from the horizontal of 0°? Express your answer with the appropriate units. WA 4 → 13 • XX x.10% 4X1 la 180 W 2 m
