WebIn 1905 Einstein extended Planck’s hypothesis to explain the photoelectric effect, which is the emission of electrons by a metal surface when it is irradiated by light or more … WebThe Photoelectric Effect. In 1886 and 1887, Heinrich Hertz discovered that ultraviolet light can cause electrons to be ejected from a metal surface. According to the classical wave …
WebDec 2, 1999 · Einstein saw that his new idea would provide a natural explanation of the photoelectric effect, i.e. the emission of electrons from metal surfaces illuminated by light. The wave theory of light was quite unable to do so. The motivation for the Nobel Prize to Einstein in 1922 was based on his discovery of the law of the photoelectric effect. WebJul 11, 2013 · 2. Light as a particle: The textbook might start off with some experimental evidence from the historic photoelectric effect to show that the wave model of light doesn’t always describe what ...
WebJul 22, 2024 · Measurements indicate that in the photoelectric effect, the energy of the electrons which leave the surface depends on the frequency of the incoming light, but not on the intensity of the light. This indicates that the incoming light consist of bundles (or quanta) of energy whose size is determined by the frequency. WebLet's explore what photoelectric effect is and how the wave theory of light fails to explain the experimental outcomes. Khan Academy is a nonprofit organizat...
WebSolution. Photoelectric can be only explained by assuming that light is made up of particle not wave because. There is no time lag b/w incident of radiation and ejection of electrons. If light were a wave than electrons will take some time to come out from metal because light wave of same energy would be distributed over large number of electrons.
