The maximum kinetic energy of emitted photoelectrons depends on

Options

  1. AIntensity of incident radiation
  2. BFrequency of incident radiation
  3. CSpeed of incident radiation
  4. DNumber of photons in the incident radiation

Correct answer

B. Frequency of incident radiation

Step-by-step solution

In photoelectric effect, the maximum kinetic energy of emitted photoelectrons depends on the frequency of incident radiation. We have K E=h v- Where is work function, which is the minimum energy required to remove electrons from the metal plate; f is frequency of incident radiation; h is Planck's constant. Therefore, (K E)_ f .
