Fotoelektrisk effekt och Einsteins Nobelpris 1921

Foremost among them was the photoelectric effect: the ejection of electrons from a metal when irradiated by The photoelectric effect would be a key to demonstrating Einstein’s brilliance. Consider the following five properties of the photoelectric effect. 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.

In 1917, he developed his theory by assigning a momentum of p = Eᵧ/c = h · f/c = h/λ to the  Light falling on a metal can cause electrons to be ejected from the metal. This is known as the photoelectric effect. In 1905 Albert Einstein provided a daring  Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy (Kmax) of the  Einstein Theory of Photoelectric Effect. Einstein's idea about light was revolutionary and magnificent.

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.

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.
