Unpolarized light with initial intensity of 38 W/m goes through three linear polarizers. The first polarizer has a transmission axis at an angle of 0 with respect to the vertical, the second polarizer has a transmission axis at an angle of +45 with respect to the vertical, and the third polarizer has a transmission axis at an angle of +75 with respect to the vertical. 29) What is the intensity of light after all the polarizers? a) 38 W/m b) 19 W/m c) 9.5 W/m d) 7.1 W/m e) 4.75 W/m 30) What angle (with respect to the vertical) should the last polarizer be at to make the final intensity of light 1/8 the original intensity? a) +15 b) +30 c) +45 d) +60 e) +90
