Polarimetry
Polarimetry is the study of the polarization of light. Light is a transverse electromagnetic wave, which means that its electric and magnetic fields oscillate perpendicular to the direction of propagation. The polarization of light refers to the direction of oscillation of the electric field vector. In most cases, the electric field vector of light oscillates in all directions perpendicular to the direction of propagation, and such light is said to be unpolarized. However, in some cases, the electric field vector of light oscillates in only one direction perpendicular to the direction of propagation, and such light is said to be polarized. Polarized light can be produced by a variety of means, including reflection, refraction, and scattering.
