WebEinstein suggests a solution Planck's explanation of the blackbody spectrum was published in 1900. Five years later, Einstein published a paper (in the very same issue as his … WebAlbert Einstein applied Planck’s radiation theory to explain the photoelectric effect where photons of light incident on the surface of a material will cause electrons to be ejected. In the photoelectric effect, the number of electrons emitted is found to increase proportionately with the intensity.
WebSimple Photoelectric Effect Albert Einstein’s Nobel Prize winning photoelectric effect has been demonstrated for many years quite effectively, yet now it can be done with simple household items. Past versions used specialized blacklights or carbon-arc lamps to show any effect. This version takes advantage of the currently popular germ sanitizer Webphotoelectric effect. Before Millikan's complete experimental validation of this law in 1914, Einstein was recommended to membership in the Prussian Academy of Science by Planck and others. Their early negative attitude toward the photon hypothesis is revealed in their signed affidavit, praising Einstein, in which they wrote: "Summing up, we may

The emitted radiation is the difference in energy between two such energy levels: ∆E = hf. We will now see how Einstein made an even bolder proposal to explain the photoelectric effect.
