Which phenomenon does NOT verify particle nature of light?
Correct answer: D. Diffraction
- A. Photoelectric effect
- B. Compton effect
- C. Pair Production
- D. Diffraction
Explanation
The phenomenon that does not verify the particle nature of light is diffraction. Diffraction is the bending of light waves around the corners of an obstacle or aperture, which is a behavior characteristic of waves. The other phenomena -Compton scattering, the photoelectric effect, and pair production-are all consistent with the particle nature of light, as they involve interactions with photons as discrete packets of energy.

About Photons and the Particle Model of Light
The particle model treats light as photons with energy E equals hf and momentum related to wavelength. Questions involve the photoelectric effect, work function, threshold frequency, stopping potential and photon energy, while distinguishing particle behaviour from the wave description of interference and diffraction.
