Which of the following phenomena proves the particle nature of photon ?
- A Interference
- B Diffraction
- C Polarisation
- D Photoelectric effect
Answer & Solution
Correct Answer
(D) Photoelectric effect
Step-by-step Solution
Detailed explanation
The photoelectric effect demonstrates that light interacts with matter as discrete "packets" or particles of energy (photons). Phenomena like interference, diffraction, and polarisation are exclusively explained by the wave nature of light. D) Photoelectric effect
