The maximum kinetic energy of emitted electrons in a photoelectric effect does not depend upon

Options

  1. Awavelength
  2. Bfrequency
  3. Cintensity
  4. Dwork-function

Correct answer

C. intensity

Step-by-step solution

According to Einstein's photoelectric equation maximum kinetic energy, aligned K_ &=e V₀=h v- ₀ &=h (v-v₀ )=h c ( 1 - 1 ₀ ) aligned Hence, in photoelectric effect, maximum kinetic energy of emitted photoelectrons depends on work function of metal surface, frequency and wavelength of incident radiation but does not depend on intensity of incident radiation.
