Question

Horizontally polarized light is transmitted through a polarizer whose transmission axis is horizontal. The light enters a container with a sugar solution and is then incident on a second polarizer whose transmission axis is vertical.

N10/4/PHYSI/HPM/ENG/TZ0/17

When the second polarizer is rotated by a small angle, no light is transmitted through the second polarizer. The explanation for this observation is that the sugar solution

A.     causes destructive interference.

B.     rotates the plane of polarization of light.

C.     can only transmit vertically polarized light.

D.     refracts light so no light is incident on the second polarizer.
