In photoelectric effect, light exhibits:
Correct answer: C. Particle nature
- A. Wave nature
- B. Both wave and particle nature
- C. Particle nature
- D. All of these
Explanation
The phenomenon of photoelectric effect cannot be explained if we assume that light consists of waves and energy is uniformly distributed over its wavefront. It can only be explained by assuming light consists of corpuscles of energy known as photon and each photon is absorbed by a single electron. Thus it shows the corpuscular nature of light.

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.
