Polarization is the phenomenon in which the vibrations of light waves are restricted to only one plane perpendicular to the direction of propagation.
👉 Normally, light vibrates in all planes (unpolarized light).
👉 After polarization, light vibrates in one plane only (plane polarized light).
Malus’ Law states that:
👉 When polarized light passes through an analyzer, the transmitted intensity depends on the angle between the transmission axes.
