Light can become
polarized by scattering off surfaces, such

polarized light is sent into such a waveguide, its polarization state continues to change
as it propagates in the waveguide and consequently, the photons exchange spin angular momentum with the waveguide.

polarized light — a specialized kind of
light used to reduce the glare off computer monitors and take clearer photographs.
Pulsars reveal the magnetic field in neighboring reaches of space because they typically emit
polarized light — radio waves that vibrate in a particular plane
as they travel through space.
