WebDec 1, 2024 · Overview of the Photoelectric Effect. The photoelectric effect is studied in part because it can be an introduction to wave-particle duality and quantum mechanics. When a surface is exposed to sufficiently energetic electromagnetic energy, light will be absorbed and electrons will be emitted. The threshold frequency is different for different ... WebApr 12, 2024 · Photoelectric effect is the emission of electrons when electromagnetic radiations having sufficient frequency incident on certain metal surfaces. We call the emitted electrons as photoelectrons and the current they constitute as photocurrent. The phenomenon was first observed by Heinrich Hertz in 1880 and explained by Albert …
