Only transverse waves, where oscillations are perpendicular to the direction of propagation, can be polarized. Longitudinal waves, where oscillations are parallel to the direction of propagation (like sound waves), cannot be polarized. Light can be polarized, proving its transverse nature.
Polarisation of light proves the
