Photoelectric effect caused by light falling onto the metal sodium. Mention Albert Einstein and the first thing that springs to mind is the theory of relativity, that other extraordinary supernova that burst upon 20th-century physics. Yet, incredibly, Einstein never won a Nobel Prize for relativity. Einstein's Legacy: The Photoelectric Effect Despite the popularity of Einstein's theories of relativity and his musings on black holes, Einstein's Nobel Prize in physics was actually awarded for his discovery of the photoelectric effect. This discovery revolutionized our understanding of the world around us. But what is the photoelectric effect?

Most significantly, the photoelectric effect, and the photon theory it inspired, crushed the classical wave theory of light. Though no one could deny that light behaved as a wave, after Einstein's first paper, it was undeniable that it was also a particle. In 1905, Einstein proposed a theory of the photoelectric effect using a concept first put forward by Max Planck that light consists of tiny packets of energy known as photons or light quanta. Each packet carries energy h ν {\displaystyle h u } that is proportional to the frequency ν {\displaystyle u } of the corresponding electromagnetic wave.

In 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-energetic photons. The kinetic energy of the emitted electrons depends on the frequency ν of the radiation, not on its intensity; for a When light strikes certain materials, it can eject electrons from them.

Java applet: Photoelectric effect. Albert Einstein gav slutligen förklaringen 1905​: Ljus består av partiklar (fotoner), och energi hos de är proportionell mot ljuset 

All of these properties are consistent with the idea that individual photons of EM radiation are absorbed by individual electrons in a material, with the electron gaining the photon’s energy. The photoelectric effect was explained in 1905 by A. Einstein. Einstein reasoned that if Planck’s hypothesis about energy quanta was correct for describing the energy exchange between electromagnetic radiation and cavity walls, it should also work to describe energy absorption from electromagnetic radiation by the surface of a photoelectrode. With his light quantum hypothesis Einstein could not only derive part of Planck's formula but also account directly for certain hitherto inexplicable phenomena.

The kinetic energy of the emitted electrons depends on the frequency ν of the radiation, not on its intensity; for a When light strikes certain materials, it can eject electrons from them. This is called the photoelectric effect, meaning that light (photo) produces electricity. One common use of the photoelectric effect is in light meters, such as those that adjust the automatic iris in various types of cameras. Einstein and the Photoelectric effect The photoelectric effect.
