Question

7. (15 pts) Three polarizers are arranged as shown below. Laser Vertical rotated Horizontal polarizer Polarizer of 45 polarizer at an angle light with respect to the vertical fraction (if any) of the original unpolarized light intensity is transmitted through the combination? Is light transmitted if the middle polarizer is rotated counterclockwise by 4 making it polarizer? What about if it is rotated clockwise by 450 making a horizontal polarizer? Explain your answers
