Refraction and scattering of light

Demonstrations of the science and application of light's refractive properties.

An explanation of double refraction is followed by Lawrence Bragg demonstrating its effects by means of Polaroid, a crystal of calcite and a lamp incorporating an iris diaphragm. The effects that are associated with the scattering of light are then described, each description being supplemented by a demonstration. He ends with a series of experiments in refraction effects using two pieces of Polaroid.
