Find the correct statement(s) about photoelectric effect.

Options

  1. AThere is no significant Ime delay between the absorption of a suitable tadiation and the emission of electrons
  2. BEinstein analysis gives a threshold frequency above which no electron can be emitted
  3. CThe maximum kinetic energy of the emitted photoelectrons is proportional to the frequency of incident radiatio
  4. DThe maximum kinetic energy of electrons does not depend on the intensity of radiation

Correct answer

D. The maximum kinetic energy of electrons does not depend on the intensity of radiation

Step-by-step solution

There is no significant time delay between the absorption of a suitable radiation and the emission of electrons and the maximum kinetic energy of electrons does not depend on the intensity of radiation. So, (a) and (d) are correct options.
