Answer:
When unpolarized light is transmitted through a Polaroid filter, it emerges with one-half the intensity and with vibrations in a single plane; it emerges as polarized light. A Polaroid filter is able to polarize light because of the chemical composition of the filter material.

Explanation:
When unpolarized light is transmitted through a Polaroid filter, it emerges with one-half the intensity and with vibrations in a single plane; it emerges as polarized light. A Polaroid filter is able to polarize light because of the chemical composition of the filter material. On viewing through the polaroid we find that when the polaroid is given one complete rotation about the direction of the light, one of the following is observed [MNR 1993] A) The intensity of light gradually decreases to zero and remains at zero. The intensity of the unpolarized light becomes zero. Polarisation of light is a property shown by transverse waves. The light waves which travel only in a single plane are known as polarized light waves. The process of transforming unpolarized light waves to polarized light waves is called the polarisation of light.
