![]() An alteration in the intensity of light would theoretically change the kinetic energy of the emitted electrons, with sufficiently dim light resulting in a delayed emission. The experimental results disagree with classical electromagnetism, which predicts that continuous light waves transfer energy to electrons, which would then be emitted when they accumulate enough energy. The effect has found use in electronic devices specialized for light detection and precisely timed electron emission. 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. Electrons emitted in this manner are called photoelectrons. The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. The emission of electrons from a metal plate caused by light quanta – photons. ![]()
