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.
Demonstrate how light is polarized when it reflects from dielectric surfaces, and remains unpolarized after reflecting from conducting surfaces. Read More
