Mega electron volt (MeV) definition
Mega electron volt (MeV) means the energy equal to that acquired by a particle with one electron charge passing through a potential difference of one million volts in a vacuum.
Mega electron volt (MeV) means the energy equal to that acquired by a particle with one (1) electron charge in passing through a potential
Mega electron volt (MeV) means the energy equal to that acquired by a particle with one electron charge in passing through a potential difference of one million volts in a vacuum. The current convention is to use MV for photons and MeV for electrons.
