1.	16. What is a polarised light? Write one method of obtaining polarised light.
Answer» Polarizationis the property of wave that can oscillate with more than one orientation. A light wave that is vibrating in more than one plane is referred to as unpolarised light. The process of transforming unpolarized light into polarized light is known aspolarization of light. Circular polarization-The electric field of light consists of two linear components that are perpendicular to each other, equal in amplitude, but have a phase difference of π/2. The resulting electric field rotates in a circle around the direction of propagation and, depending on the rotation direction, is called left- or right-hand circularly polarized light.
