Polarization is a process of turning . unpolarized. light to polarized light. A light wave is an electromagnetic wave that travels through the vacuum of outer space. Light waves are produced by vibrating electric charges.. INTERFERENCE FILTER. Arrangement for filtering monochromatic beam from incident white light is called interference filter.. When a narrow beam of white light is incident on the filter, it undergoes multiple reflections in the dielectric, it loses a major part of its intensity and finally emerges from the filter as a very narrow band with one or two maxima..
