The kinetic energy of photoelectrons does NOT depend upon

0.Intensity of incident radiation

1.Frequency of incident radiation

2.Wavelength of incident radiation

3.Wave number of incident radiation

Explanation

KE = hν − W. KE depends on frequency (or wavelength/wave number) but NOT on intensity. Intensity affects the number of electrons, not their individual KE.
