MCQ
The photoelectric effect was successfully explained by
- AHertz
- BPlanck
- CMillikan
- ✓Einstein
✓
Answer
Correct option: D.
Einstein
Einstein showed mathematically, the energy of the incoming photons was precisely related to the frequency or wavelength of the light shining and equal to the energy of the electrons they ejected. Einstein's explanation of the photoelectric effect was powerful evidence that energy could exist only in fixed amounts called quanta.
