Polarisation

n. making polarized, giving two opposite tendencies; condition of having polariy; phenomenon in which light waves move in one plane (also polarization)

This article is about electromagnetic waves; for other senses of this term, see polarization (disambiguation).In electrodynamics, polarization (Brit., polarisation) is the property of electromagnetic waves, such as light, that describes the direction of the transverse electric field. More generally, the polarization of a transverse wave describes the direction of oscillation in the plane perpendicular to the direction of travel. Longitudinal waves such as sound waves do not exhibit polarization, because for these waves the direction of oscillation is along the direction of travel.
