WebbThe photoelectric effect is the emission of electrons or other free carriers when light shines on a material. Electrons emitted in this way can be called photo electrons. This phenomenon is generally studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry.

Webb21 aug. 2015 · Millikan's photoemission paper of 1916 is of great historical importance because it provided the first unambiguous experimental support for Einstein's theory of the photoelectric effect. His graphical presentation of the results, for the correlation of stopping potential with frequency of the incident light on a sodium surface, is widely … WebbThe photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics. the pharma chem monthly

WebbThe Photoelectric effect is directly proportional to the incident power of the light on a given metal surface and it is also the incident light frequency. The frequency threshold exists for a specified metal. In this definite least frequency the photo-electric emission is absent. WebbThe photovoltaic effect is the generation of voltage and electric current in a material upon exposure to light. It is a physical and chemical phenomenon.

WebbFigure 1.3.1 : The photoelectric effect involves irradiating a metal surface with photons of sufficiently high energy to cause the electrons to be ejected from the metal. (CC BY-SA-NC; anonymous) The classical picture underlying the photoelectron effect was that the atoms in the metal contained electrons, that were shaken and caused to vibrate ... WebbThis could not be explained as Maxwell’s electromagnetic theory (which Hertz proved correct) predicted that the kinetic energy should be only dependent on light intensity (not frequency). The resolution would only come a few years later by Einstein when he would provide an explanation of the photoelectric effect.
