Polarization of light is possible because light is:
AA longitudinal wave
BA transverse wave
CBoth transverse and longitudinal
DParticle only
Answer & Solution
Correct answer: B. A transverse wave
Polarization (restricting oscillation to a single plane) is a property unique to transverse waves. Light's electric field oscillates perpendicular to propagation direction, so it can be polarized. Sound (longitudinal) cannot be polarized.
