MCQ
Which theory of light explains the photoelectric effect?
- ✓Electromagnetic theory
- BMagnetic theory
- CElectric theory
- DWave theory
✓
Answer
Correct option: A.
Electromagnetic theory
According to the electromagnetic theory, the photoelectric effect can be attributed to the transfer of energy from the light to an electron. From this point of view, an alteration in the intensity of light will induce changes in the kinetic energy of the electrons emitted from the metal.
