Quick answer: Light comes in photons of energy E = hf. In the photoelectric effect a photon ejects an electron only if hf is at least the work function φ, and the electron then has maximum kinetic energy Kmax = hf − φ. This Physics 11-12 quiz checks photoelectric effect with 10 multiple-choice questions and instant feedback; every answer comes with a short explanation.
