Q17.Which of the following phenomena does not explain by wave nature of light. A. reflection B. diffraction C. photoelectric effect D. interference E. polarization Choose the most appropriate answer from the options given below: (1) E only (2) B, D only (3) C only (4) A, C only

What This Question Tests

This question tests the conceptual understanding of which phenomena of light are explained by its wave nature and which require its particle (quantum) nature. The photoelectric effect is a key phenomenon that led to the quantum theory of light and cannot be explained by classical wave theory.
