- Energy and power
- Widely used in nuclear, atomic and particle physics
One electron volt is the energy acquired by an electron when accelerated through a potential difference of 1 volt.It is equal to 1.602 Ã— 10âˆ’19 joules.
- Visible light has photon energy of 1.6 eV to 3.4 eV
Commonly encountered when dealing with atomic and nuclear processes
- Commonly subdivided into millielectornvolts and microelectronvolts
- There are 1,000,000 electronvolts in a Megaelectronvolt, the units can be further expanded into Gigaelectronvolt, etc.
