NettetTo understand plane polarisation light better, let us know the concept of transverse waves. They are produced when the movement of particles in the wave is perpendicular to the direction of the wave’s motion. Ripples in water and the motion of sound waves could be an example of transverse waves. Longitudinal waves are referred to as particles ... A polarizer or polariser (see spelling differences) is an optical filter that lets light waves of a specific polarization pass through while blocking light waves of other polarizations. It can filter a beam of light of undefined or mixed polarization into a beam of well-defined polarization, that is polarized light.
