Question

What is MeV?Why it is so named?
​

Answer 1

Answer:

The original article was at Electronvolt. ... It is commonly used with the SI prefixes milli-, kilo-, mega-, giga-, tera-, or peta- (meV, keV, MeV, GeV, TeV and PeV respectively). Thus meV stands for milli-electron volt. Atomic properties like the ionization energy are often quoted in electron volts.

Answer 2

$<marque>$

MeV and meV are multiples and submultiples of the electron volt unit, (eV), referring to: 1 MeV, 1 megaelectronvolt = 1,000,000 eV, and. 1 meV, 1 millielectronvolt = 0.001 eV.
