WebJan 30, 2024 · The Photoelectric Effect. Light incident on a metal plate may cause electrons to break loose from the plate surface (Fig. 1). This interaction between light and electrons is called the photoelectric effect. The photoelectric effect provided the first conclusive evidence that beams of light was made of quantized particles. WebThis phenomenon is known as the photoelectric effect. Electrons that are emitted in this process are called photoelectrons. The experimental setup to study the photoelectric effect is shown schematically in Figure 6.8. The target material serves as the cathode, which becomes the emitter of photoelectrons when it is illuminated by monochromatic ...
