Q 9 A quarter wave plate is placed in between a polarizer and a photo director When the optic axis of the quarter wave plate is kept initially parallel to the pass axis of the polarizer and perpendicular to the direction of light propagation The intensity of light passing through the quarter wave plate is measured to be Io see figure If the quarter wave plate is now rotated by 45 about an axis parallel to the light propagation what would be the intensity of the emergent light measured by the photo director
