Right Answer is: C

SOLUTION

  • The photoelectric effect shows the discrete nature of the photon and demonstrates the particle-like behavior of the photon.
  • The photoelectric effect is based on the particle nature of radiation since it is a phenomenon in which the interaction of the particle takes place with the matter as shown:

          ​

  • The photoelectric effect is the phenomenon in which electrons are ejected from the surface of a metal when the light of sufficient frequency falls on it.
  • The minimum energy required to remove an electron is called the work function of the material and any excess photon energy goes into the kinetic energy of the photoelectron.


The graph shown below represents the relationship between the incident light and the KE of the electron ejected from the metal surface:
