Polarized by E&M Light is an electromagnetic wave, EM wave. The electric and magnetic fields both oscillate perpendicularly to the direction of propagation, making light a transversely polarized wave. As light travels through a medium, the oscillating electric field has an effect on electrically charged objects in the medium (mostly electrons). Oscillating charges create fluctuating electric (and magnetic) field vectors. Polarized light has a single direction for fluctuations of electric field vectors. Unpolarized light has no preferred direction for fluctuations...
