Photoelectric effect past paper questions

A2 Physics 9702 · Quantum physics. 1 understand that photoelectrons may be emitted from a metal surface when it is illuminated by electromagnetic radiation 2 understand and use the terms threshold frequency and threshold wavelength 3 explain photoelectric emission in terms of photon energy and work function energy 4 recall and use hf = Φ + 2 1 mvmax 2 5 explain why the maximum kinetic energy of photoelectrons is independent of intensity, whereas the photoelectric current is proportional to intensity
