M7-33. Depolarization By Scattering - Wax Paper
Purpose
Demonstrate how scattering can depolarize light.
Equipment
Baffle with polaroid, mounted rotating polaroid, and wax paper with overhead projector.

Description
A polaroid rests in a baffle on the overhead projector platform. A second polaroid is mounted on the bottom lens of the mirror mount. Rotating the upper polaroid verifies the transverse nature of the light. A sheet of wax paper, placed on the polaroid sheet on the platform, depolarizes the light so that the field cannot be made dark by rotating the upper polaroid. This also demonstrates that it is not optical activity.
