Will the number of photoelectrons ejected be same if intensity remains same but frequency is different?

Question

Assuming incident frequency is above threshold frequency

In: Physics

Answer 1

That’s kind of a tricky question because raising frequency does mean raising the energy level of each photon. If the amount of photons is constant, the overall energy and the intensity rises. If the intensity is constant, the number of photons must be smaller in order to carry the same sum of energy with them.
