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 ...
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 ...
Einstein's paper on the photoelectric effect is sixth on this list. The following chronology of Einstein's scientific discoveries provides a context for the publications listed below, and clarifies the major themes running through his work. Einstein's scientific career can be broadly divided into to periods.
The photo-electric quantum theory was the work cited when Einstein was awarded the Nobel Prize in Physics in 1921. Suspicious of the general adulation of Einstein, Lenard became a prominent skeptic of relativity and of Einstein's theories generally; he did not, however, dispute Einstein's explanation of the photoelectric effect.
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 ...
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.
Einstein's photon had an energy proportional to its frequency and also explained an unpublished law of Stokes and the photoelectric effect. [5] This published postulate was specifically cited by the Nobel Prize in Physics committee in their decision to award the prize for 1921 to Einstein.
1905 – Einstein explains the photoelectric effect by extending Planck's idea of light quanta, or photons, to the absorption and emission of photoelectrons. Einstein would later receive the Nobel Prize in Physics for this discovery, which launched the quantum revolution in physics.
