plane of polarization
Quick Summary
Polarization is a property of electromagnetic radiation, like light, where the direction and magnitude of the vibrating electric field are related in a specific way. Light waves are transverse, meaning their electric vectors vibrate perpendicular to the direction the wave travels.12
Unpolarized light has electric vectors pointing in random directions. Plane-polarized light, however, has electric vectors vibrating in a single, fixed direction. The plane containing the propagation direction and the electric vector is called the plane of polarization. Light can become plane-polarized through processes like reflection or by passing through special filters. Circular polarization is another type where the electric vector rotates as the wave moves.13
