The demonstration shows the properties of polarization using three polarizer sheets. When two polarizers are placed on top of each other, they can block out the light if rotated correctly. When a third is placed in between at a 45 degree angle, some light again gets through.
* Equipment seen in the video may vary from equipment used in ND Demonstrations. See information and images below for ND equipment and setup.
Setup:
Place the apparatus on the document camera.
Place one polarizer sheet on top and rotate it to block out all the light.
Place the other polarizer sheet in the middle of the apparatus and rotate it to see how some light is allowed to pass at the correct angle.
