Introduction
When electromagnetic radiation passes from one media into another, some of the radiation usually reflects from the surface of
the new medium. In this experiment, you will find that the magnitude of the reflected signal depends on the polarization of the
radiation. In fact, at a certain angle of incidence—known as Brewster’s Angle—there is an angle of polarization for which no
radiation will be reflected. (Check your textbook for more information on Brewster’s Angle.).
