Question

What is the conclusion of the photoelectric effect?

Answer 1

The conclusions of the photoelectric effect are listed below

1. The photoelectric effect is caused when the photons in the light interact with the electrons in the metal
2. Each of the photons interacts with one electron.
3. The energy of the incident photon is used in liberating the electrons from the surface and to impart energy to the ejected electrons.
4. The minimum energy required to eject electrons from the surface is called the work function.
5. The energy of the incident photon should be greater than the work function.

Hence, the conclusion of the photoelectric effect is that the energy in light comes in small packets.
