Student Manual

Brewster's angle is the angle of incidence at which p polarized light is perfectly transmitted through a transparent dielectric surface such as glass, without any reflection. In this experiment, you will find Brewster's angle by measuring the reflectance of a glass slide for p polarized light. You will also measure the reflectance for s polarized light and light polarized at 45° with respect to the incidence plane. Furthermore, the Brewster angle will be used to calculate the refractive index of glass.
