In 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect. Einstein theorized that the energy in each quantum of light was equal to the frequency of light multiplied by a constant, later called the Planck constant. A ...
Table of contents of the journal Annalen der Physik for the issue of June 1905. Einstein's paper on the photoelectric effect is sixth on this list. The article "Über einen die Erzeugung und Verwandlung des Lichtes betreffenden heuristischen Gesichtspunkt" ("On a Heuristic Viewpoint Concerning the Production and Transformation of Light") [einstein 1] received 18 March and published 9 June ...
(Einstein was formally awarded his PhD on 15 January 1906.) [76] [77] [78] Four other pieces of work that Einstein completed in 1905—his famous papers on the photoelectric effect, Brownian motion, his special theory of relativity and the equivalence of mass and energy—have led to the year being celebrated as an annus mirabilis for physics ...
The following outline is provided as an overview of and topical guide to Albert Einstein: Albert Einstein – German-born theoretical physicist. He developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). [1] [2]: 274 Einstein's work is also known for its influence on the philosophy of science.
To explain the photoelectric effect, Albert Einstein assumed heuristically in 1905 that an electromagnetic field consists of particles of energy of amount hν, where h is the Planck constant and ν is the wave frequency.
Building on Einstein's proposal that the photoelectric effect can be described using quantized energy transfers and by Einstein's separate proposal, from special relativity, that mass at rest is equivalent to energy via =, de Broglie proposed that matter in motion appears to have an associated wave with wavelength = / where is the matter ...
In 1922 Albert Einstein was awarded the 1921 Nobel Prize in Physics, [1] "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect". This refers to his 1905 paper on the photoelectric effect, "On a Heuristic Viewpoint Concerning the Production and Transformation of Light", which was well ...
In 1905, Albert Einstein published a paper in which he proposed that many light-related phenomena—including black-body radiation and the photoelectric effect—would be better explained by modelling electromagnetic waves as consisting of spatially localized, discrete energy quanta. [10] He called these a light quantum (German: ein Lichtquant ...
