In the photoelectric effect, what happens to the emitted electrons if the frequency of the incident light is just at the threshold frequency?
They are emitted with maximum kinetic energy
They are emitted with zero kinetic energy
They are not emitted
They are emitted with negative kinetic energy
At the threshold frequency, the energy of the incident photons is equal to the work function, resulting in emitted electrons having zero kinetic energy.
