Suppose that you take the lenses out of a pair of polarized sunglasses and place one on top of the other. Rotate one lens 90° with respect to the normal position of the other lens
Early in the morning, look directly overhead at the sunlight coming down. What would you see? A) The lenses would look completely dark, since they would transmit no light.

D) You would see some light, and the intensity would be the same as if you had looked through only one lens. E) You would see some light, and the intensity would be greater than if you looked through only one lens.
