Which phenomenon provides conclusive evidence for the transverse wave nature of light?

A. Interference
B. Diffraction
C. Polarization✓ Correct Answer
D. Photoelectric effect

💡 Solution & Explanation

Polarization provides conclusive experimental evidence confirming the transverse wave nature of light because only waves oscillating perpendicularly to their direction of propagation can be filtered into specific vibration planes. Phenomena like interference and diffraction occur with both transverse and longitudinal waves, failing to distinguish between wave types uniquely. Light waves are electromagnetic waves consisting of mutually perpendicular electric and magnetic fields.
