M7-18: POLAROID SUNGLASSES

ID Code: M7-18
Purpose: Demonstrate how polaroid sunglasses work using a pair of clip-on polaroid sunglasses.
Description: A collimated light source is set up to reflect off a dielectric surface onto a screen. The polaroid sunglass lens is placed in the glare and rotated to demonstrate that it has a polarization effect, and removes the glare. The photograph at the left shows the polaroid sunglasses with their polarization axis parallel to the reflecting dielectric surface; at the right the polaroid axis is perpendicular to the reflecting surface, removing the glare.
