Photoelectric effect - Wikipedia

WebbThe photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material.Electrons emitted in this manner are called photoelectrons. The phenomenon is studied in condensed matter physics, and solid state and quantum chemistry to draw inferences about the properties of atoms, molecules and solids. . The … WebbThe photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839, who found that certain materials would produce small amounts of electric current when exposed to light. In 1905, Albert Einstein described the nature of light and the photoelectric effect on which photovoltaic technology is based, for which he later won a Nobel prize in … WebbQuestions on the Photoelectric Effect Q1.
