What is Kinetic energy of photoelectrons?

The energy of the light wave was proportional to its brightness, which is related to the wave's amplitude. There is an effect of light amplitude and frequency on the rate of electron ejection, as well as the kinetic energy of the photoelectrons. The kinetic energy of emitted photoelectrons should increase with the light amplitude.
