In a photoelectric experiment, if the frequency of light is just above the threshold frequency, what can be said about the emitted electrons?

In a photoelectric experiment, if the frequency of light is just above the threshold frequency, what can be said about the emitted electrons?

Step 1: Understand the threshold frequency. This is the minimum frequency of light needed to release electrons from a material.
Step 2: Recognize that when light of frequency just above the threshold frequency hits the material, it can release electrons.
Step 3: Know that the energy of the incoming light is used to overcome the work function, which is the energy needed to release an electron.
Step 4: If the frequency of light is just above the threshold frequency, it means the energy provided by the light is just enough to overcome the work function.
Step 5: Since all the energy from the light is used to overcome the work function, the emitted electrons will have no extra energy left over.
Step 6: Therefore, the emitted electrons will have zero kinetic energy.
