When light enters a diamond from air, it is refracted (bent) and then reflected off the back of the diamond. The light is then refracted again as it exits the diamond.

Interference is not the main cause of the brilliance of diamond.<\/p>\n<p>(b) Diffraction of light is the bending of light as it passes through a narrow opening or around an obstacle. This is caused by the wave nature of light. Diffraction is not the main cause of the brilliance of diamond.<\/p>\n<p>(c) Polarization of light is the process of restricting the direction of oscillation of light waves. This can be done by passing light through a polarizing filter.
