In three to four sentences, explain how the photoelectric effect supports a particle model of electromagnetic radiation. As part of your response, evaluate the idea that radiation frequency and intensity highlight how the wave model is inadequate to explain the photoelectric effect.(4 points)
The photoelectric effect supports a particle model of electromagnetic radiation by showing that light behaves like particles (photons) when interacting with matter - individual photons are absorbed by electrons, causing them to be ejected from a material. The fact that the kinetic energy of the ejected electrons is dependent on the frequency of the incident light (rather than its intensity) contradicts wave theory, which predicts that the energy of the ejected electrons should be proportional to the intensity of the light. This inconsistency between the predictions of wave theory and the experimental results of the photoelectric effect provides strong evidence in favor of a particle model of light.
