Electron Volt
Unit of energy of moving particles. Given by the kinetic energy acquired by an electron losing one volt of potential.
eV = 1.60217733x10-19J
| Kilo electron Volt (keV) | = | 1,000 eV | Mega electron Volt (MeV) | = | 106eV | |
| Giga electron Volt (GeV) | = | 1,000,000,000 eV | Tera electron Volt (TeV) | = | 1012eV |
Electronvolts are used as a measure of the energy of cosmic rays and high-energy photons.
| Binding energy on an electron in an atom | ~1 eV |
| the photon energy of visible light | 1.6 to 3.4 eV |
| X-rays | ~1000 eV (1 keV) |
| energy-equivalent (E=mc2) of the mass of a proton | ~1 GeV |
| kinetic energy of a flying mosquito | ~1 TeV |
