To study Polarization by reflection,
To determine Brewster's angle for a glass surface,
To calculate the index of refraction of a glass material using Brewster's angle measurement,
To investigate the variation of light intensity transmitted through two polarizing filters with respect to the angle of transmission axes of both polarizers,
To verify, polarized light by showing that the intensity of light passed through two polarizers depends on the square of the cosine of the angle between the two polarization axes.
