Use the following information to answer the next question. Classical wave theory and quantum physics make different predictions about the effect of incident electromagnetic radiation on a photoelectric surface. Four Photoelectric Effect Predictions 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. Numerical Response 7. Match each of the predictions above with the appropriate theory of physics as labelled below. (There is more than one correct answer.)
