- ACorpusular theory of light
- BWave nature of light
- CBohr’s theory
- ✓Quantum theory of light
✓
Answer
Correct option: D.
Quantum theory of light
d
(d) Quantum theory of light can explain the photoelectric effect that if a quanta of photon is incidented on the metal surface, the energy of photon breaks the electronnucleus interaction and thus an electron is emitted from the metal surface. Since some energy is required to break that interaction to emit the electron, so the photoelectric effect takes place from the metal surface only if the energy of photon is greater than the work function of that metal.
