Match predictions

Classical wave theory and quantum physics make different predictions about the effect of incident electromagnetic radiation on a photoelectric surface.| Four Photoelectric Effect Predictions 1 Low-intensity electromagnetic radiation incident on a photoelectric surface for long periods of time will cause photoemission. 2 High-intensity electromagnetic radiation will not cause photoemission unless its frequency is greater than the photoelectric surface's threshold frequency. 3 The energy of the emitted photoelectrons will increase if the intensity of the incident electromagnetic radiation is increased. 4 The energy of the emitted photoelectrons is independent of the intensity of the incident electromagnetic radiation. Match each of the predictions above with the appropriate theory of physics as labelled below. (There is more than one correct answer.) Prediction: Appropriate Theory: Classical wave theory Quantum physics State your answer as a 4 digit number matching the order of the blanks. (eg. if you think predictions #5 and #6 are for classical and #7 and #8 are for quantum then you'd state your answer as 5
