What is photoelectric effect? State the result of photoelectric effect experiment that could not be explained on the basis of laws of classical physics. Explain this effect on the basis of quantum theory of electromagnetic radiations.

Options

  1. APhotoelectric effect is the emission of electrons from a material when it is exposed to light. The result that
  2. BPhotoelectric effect is the scattering of light when it strikes a surface. The result that could not be explai
  3. CPhotoelectric effect is the emission of light from a material when it is exposed to high-energy electrons. The
  4. DPhotoelectric effect is the absorption of light energy by a material. The result that could not be explained b

Correct answer

A. Photoelectric effect is the emission of electrons from a material when it is exposed to light. The result that

Step-by-step solution

Correct Option is : (A) Photoelectric effect is the emission of electrons from a material when it is exposed to light. The result that could not be explained by classical physics is the observation that the kinetic energy of emitted electrons depends on the frequency, not the intensity, of incident light.
