Answer the following question given this paragraph: 

27.8 Polarization • Polarization is the attribute that wave oscillations have a definite direction relative to the direction of propagation of the wave. • EM waves are transverse waves that may be polarized. • The direction of polarization is defined to be the direction parallel to the electric field of the EM wave. • Unpolarized light is composed of many rays having random polarization directions. • Light can be polarized by passing it through a polarizing filter or other polarizing material. The intensity I of polarized light after passing through a polarizing filter is I = I 0 cos 2 θ, where I 0 is the original intensity and θ is the angle between the direction of polarization and the axis of the filter. • Polarization is also produced by reflection. • Brewster’s law states that reflected light will be completely polarized at the angle of reflection θ b , known as Brewster’s angle, given by a statement known as Brewster’s law: reflected light travel and.
