Unpolarized light with intensity I0 is initially incident on a first polarizer of a set of polarizers. The first polarizer has a polarizing direction which is vertical. a) A second polarizer has an angle of 90° to the vertical. What is the intensity of light after the second polarizer in terms of the initial intensity? b) Now you place a third polarizer in between the two others. The third one has a polarizing angle of 30° to the vertical. What is the intensity of light after the first, the second, and the third polarizer in terms of the initial intensity?
