Question

Quizplus · Accepted Answer

The maximum kinetic energy of photoelectrons depends on the frequency (or energy) of the incident photons, as described by the Einstein photoelectric equation: KEmax = hf - φ, where h is Planck's constant, f is the frequency of the incident photons, and φ is the work function of the metal. The intensity, area, thickness, and current do not directly affect the kinetic energy of the photoelectrons.
