Polarization establishes that light is:
AA longitudinal wave
BParticle stream
CA TRANSVERSE wave (only transverse waves can be polarized)
DSound
Answer & Solution
Correct answer: C. A TRANSVERSE wave (only transverse waves can be polarized)
Polarization is restricting the oscillation direction of the electric field. Only transverse waves (oscillations perpendicular to propagation) can be polarized. Sound (longitudinal) cannot. This is decisive evidence light is transverse EM.
