This book compiles experiments on polarization of light. The necessary theories, e.g. wave theory in chapter 1, electromagnetic theory in chapter 3, and quantum theory in chapter 5 are discussed at length. The second chapter determines the optical activity of transparent cellophane film using ordinary white light. The fourth chapter verifies Fresnel''s equations using sodium source. In the sixth chapter laws of reflection and refraction using a rectangular glass slab and a laser source are verified along with the variation of reflectance and transmittance of laser beam with angle of incidence.
