Question

30. Plane-polarized light is incident normally on a polarizer which is able to rotate in the plane perpendicular to the light as shown below. Diagram 1 incident light (intensity = 8 W m^-2) transmitted light (intensity = 2 W m^-2) polarizer Diagram 2 incident light (intensity = 8 W m^-2) transmitted light polarizer In diagram 1, the intensity of the incident light is 8 W m^-2 and the transmitted intensity of light is 2 W m^-2. Diagram 2 shows the polarizer rotated 90° from the orientation in diagram 1. What is the new transmitted intensity? A. 0 W m^-2 B. 2 W m^-2 C. 6 W m^-2 D. 8 W m^-2
