PhysicsNEET 2020Photoelectric effect and Einstein's equation

Dual Nature of Radiation and Matter

Light of frequency 1.5 times the threshold frequency is incident on a photosensitive material. What will be the photoelectric current if the frequency is halved and the intensity is doubled?

  1. A.Doubled
  2. B.Four times
  3. C.One-fourth
  4. D.Zero

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
