When unpolarized light falls on the surface of a block of glass, the reflected light is partially polarized. If the angle of incidence is tan-1n, where n is the refractive index of the glass, the reflected light is completely linearly polarized. (i) Describe the apparatus you would use and the experiments you would perform in order to verify these statements for a sample of glass of known refractive index. (ii) Why will it be necessary, if very accurate results were required to use monochromatic light to verify the second statement?
