Unpolarized light of intensity 1 mW/m2 is incident on a plane polarizing filter whose axis makes an angle 300 with the vertical. Then the light passes through a second filter whose axis is horizontal. What is the intensity of the light after it emerges from the second filter? (Hint: When unpolarized light of intensity I0 passes thru a linear polarizer, the transmitted intensity is I0/2. This is because unpolarized light is a mix of random polarization directions (i.e., direction of the E field) and on the average only ½ gets through. See diagram below.) a) .125 mW/m2 b) .375 mW/m2 c) none of these.
