Question

the energy of emitted photo electron depends up on .......a.intensity of light.........b......wave length of light.......c......work function of metal....d...none of these​

Answer 1

Answer:

a When a photoelectric effect is observed, the number of electrons ejected is proportional to the intensity of the incident light. However, the maximum kinetic energy (KEMAX) of the photoelectrons is independent of the light intensity.

b Thus the kinetic energy of photoelectrons depends on the frequency of incident light and is independent light. Hence there is no effect of intensity of light on the kinetic energy of emitted photoelectrons

c. Thus kinetic energy of the emitted photoelectrons depends on wavelength, frequency of the incident photon and work function of the metal but does not depend on the intensity.
