In three to four sentences, explain how the photoelectric effect supports a particle model of electromagnetic radiation. evaluate the idea that radiation frequency and intensity highlights how the wave model is inadequate to explain the photoelectric effect

The photoelectric effect supports a particle model of electromagnetic radiation by demonstrating that light is composed of discrete particles called photons. These photons have energy proportional to their frequency, which explains why increasing the frequency of light increases the energy of the electrons emitted in the photoelectric effect. This relationship between frequency and energy contradicts the wave model, which predicts that increasing intensity (amplitude) should increase the energy of the emitted electrons. This discrepancy suggests that the wave model is inadequate in explaining the photoelectric effect, providing further evidence for the particle nature of light.
