An electron moves through a region of crossed electric and magnetic fields. The electric field E = 2 000 V/m and is directed straight down. The magnetic field B = 0.80 T and is directed to the left. Specify the directions of electric and magnetic forces on the electron if it moves into the paper. For what velocity v of the electron will the electric force exactly cancel the magnetic force?

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...
