The experimental proof of particle nature of light is:
Correct answer: B. Photo electric effect
- A. Pair production
- B. Photo electric effect
- C. Davison-Germer experiment
- D. De- Broglie concept
- E. Compton's effect
Explanation
The experimental proof of the particle nature of light is: Photoelectric effect. This observation supported the particle-like behavior of light, as the energy transfer from the incident photons to the electrons could only be explained by treating light as discrete particles. So option B is the correcct answer.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
