What do keV and MeV stand for?

Explanation:
The main idea is that keV and MeV are energy units used for subatomic particles and photons. The “electron volt” is the amount of energy gained by an electron when it moves through a potential difference of one volt. The prefixes tell you the scale: kilo- means a thousand, and mega- means a million. So keV is a thousand electron volts, and MeV is a million electron volts. In XRF and similar contexts, photon energies are described in these units because they’re small enough to be practical for individual photons, unlike larger energy units. It’s why you’ll see X-ray energies discussed in keV or MeV rather than kilovolts, joules, or kilowatt-hours.
