alleryWhich of the following phenomena conclusively proves that **light is a transverse wave**?
AReflection
BRefraction
CInterference
DPolarization
Answer & Solution
Correct answer: D. Polarization
Only transverse waves can be polarized (oscillations restricted to one plane perpendicular to propagation).
Reflection, refraction and interference occur for longitudinal waves too — they don't distinguish wave type.
