POLARIZATION OF LIGHT
... Consequently, two coherent plane-polarized light waves whose planes of oscillations are mutually perpendicular produce an elliptically polarized light wave when superposed on each other. At a phase difference of zero or π, the ellipse degenerates into a straitght line, and plane-polarized light is ...
