Which of the following conclusion is correct regarding photoelectric effect?

Options

  1. AEnergy of a photon depends upon frequency of light absorbed.
  2. BEnergy of a photon depends upon intensity of light.
  3. CKinetic energy of electrons increases due to increase in intensity of light.
  4. DAll the energy of photon is absorbed by metal súrface.

Correct answer

A. Energy of a photon depends upon frequency of light absorbed.

Step-by-step solution

Energy of photon depends upon frequency and not on intensity. As on increasing the intensity of light of a particular frequency v , the number of electrons ejected increases but not their kinetic energy.
