Polarized light is light in which the waves vibrate in a specific direction. It can be produced by passing light through a special “polarizing” filter. Sunglasses cut down glare on a bright sunny day. Some sunglasses have lenses made of polarizing material. The light waves that vibrate in the same plane as the polarizing material can pass through, but other waves are reflected or absorbed. In this experiment, you will use a computer-interfaced Light Sensor to study the transmission of light through Polaroid filters.
In this experiment, you will
Measure the intensity of transmitted light.
