In case of photoelectric effect

WebJan 10, 2024 · The photoelectric effect is a phenomena which increases only when a large number of surface electrons are knocked out, that is, a large number of surface electrons collide with collide with incoming photons. Increasing frequency increases the energy of each photon, but increasing intensity increases the number of photon. WebWhen these free electrons are captured, an electric current results that can be used as electricity. The 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.

WebTypically, one photon is either energetic enough to cause emission of an electron or the energy is lost as the atom returns back to the ground state. If excess photon energy is absorbed, some of the energy liberates the electron from the atom and the rest contributes to the electron's kinetic energy as a free particle. WebThe photoelectric effect is the process that involves the ejection or release of electrons from the surface of materials (generally a metal) when light falls on them. The photoelectric effect is an important concept that …
