Photoelectric effect explained
Measuring Planck’s Constant Using the Photoelectric Effect
The photoelectric effect - waves as particles. An introduction and values for the work function. The Photoelectric Effect ... This can be explained like this. The free electrons are held in the metal in a "hole" in the electric field, this is called a potential well. Energy has to be supplied to them to enable them to escape from the surface.

The photoelectric effect was – well known by the end of the 19th century. Its explanation was one of Einstein’s first applications of his photon model for light. He devised an equation relating the energy of the photoelectrons to the frequency of the light and the work function of …

The Photoelectric Effect. In photoelectric emission, light strikes a material, causing electrons to be emitted. The classical wave model predicted that as the intensity of incident light was increased, the amplitude and thus the energy of the wave would increase. This would then cause more energetic photoelectrons to be emitted.

The Photoelectric Effect. 1. In the early 1900’s, conducted experiments that could not be explained using the wave theory of light. a. One experiment involved the photoelectric effect. The photoelectric effect. is the emission of electrons from a metal when light shines on the metal. Figure 3 on page 99.

The photoelectric effect was first explained by Albert Einstein in 1905. When a light of high enough frequency is shone on a metal, electrons are ejected from the metal. According to Einstein’s explanation, when a photon hits the metal, the electrons will be ejected from the metal with a range of kinetic energies from 0 J up to some maximum kinetic energy given by

This conjecture nicely explained the photoelectric effect experiment. In this experiment, the maximum kinetic energy of the electrons leaving the surface of a metal when irradiated by quasi-monochromatic light is shown to depend upon the WAVELENGTH (or colour) of the light, and NOT upon the intensity of the light.
Photoelectric Effect Definition and Explanation
Einstein's theory explained many features of the external photoelectric effect, including why the maximum energy of electrons ejected from a metal is independent of the intensity of the incident light. According to his theory, the maximum energy of a dislodged electron depends only on the energy with which a photon strikes the electron; the ...

The photoelectric effect was explained by Einstein when he conjectured that Planck’s bundles of energy (i.e. photons) were “knocking loose” the electrons—but only if the photons had enough energy to do the job (a two year old isn’t able to knock a football player off his feet, but a bull undoubtedly could).
