In a photoelectric effect experiment at a frequency above cut off, the number of electrons ejected is proportional to:
A)their kinetic energy
B)their potential energy
C)the work function
D)the frequency of the incident light
E)the number of photons that hit the sample

Question

Quizplus · Accepted Answer

In the photoelectric effect, the number of electrons ejected is directly proportional to the number of photons hitting the sample. This is because each photon has the potential to eject a single electron, assuming the photon's energy is above the material's work function threshold.
