Megaelectronvolt
Megaelectronvolt[edit | edit source]
A megaelectronvolt (MeV) is a unit of energy equal to one million electronvolts. It is commonly used in particle physics and nuclear physics to measure the energy of particles.
Definition[edit | edit source]
The megaelectronvolt is defined as 1 MeV = 1.602176634×10-13 joules. This conversion factor is derived from the elementary charge, which is the charge of an electron or proton.
Usage in Physics[edit | edit source]
In particle physics and nuclear physics, the megaelectronvolt is used to measure the energy of particles. For example, the mass-energy equivalence principle, derived from Albert Einstein's theory of special relativity, states that the energy (E) of a particle is equal to its mass (m) times the speed of light (c) squared. This energy is often expressed in MeV.
Relation to Other Units[edit | edit source]
The megaelectronvolt is related to other units of energy. For example, 1 MeV is equivalent to:
