Photoelectric effect

OverviewEmission mechanismHistoryUses and effectsCompeting processes and photoemission cross sectionExternal links

The photons of a light beam have a characteristic energy, called photon energy, which is proportional to the frequency of the light. In the photoemission process, when an electron within some material absorbs the energy of a photon and acquires more energy than its binding energy, it is likely to be ejected. If the photon energy is too low, the electron is unable to escape the material. Since

One electrode--the anode--permits electrons to flow out of it. The other--the cathode--receives them. The energy is stored in the particular compounds that make up the anode, cathode and the

Photoelectricity

Since the photoelectron has a kinetic energy of 5.0eV, the energy of the photon must be the sum of both energies, as energy is conserved. One electron volt (eV) is equal to 1.6 ⋅ 10^-19 joules. Therefore, the energy of the photon can be calculated by adding the kinetic energy of the photoelectron to the work function.
