FAQs
What is an Electron Volt (eV)?
An electron volt (eV) is a unit of energy commonly used in atomic and particle physics. It is defined as the amount of energy gained or lost by an electron when it moves across an electric potential difference of one volt.
1 eV = 1.602176634 × 10−19 J
Why is the electron volt preferred in physics?
The electron volt is convenient for expressing the small energy scales typical in atomic and particle physics, where using Joules would involve unwieldy powers of ten.
When is the eV to Joules conversion used?
— Atomic physics: Calculating the energy of photons or electrons.
— Particle physics: Expressing the energy of particles in accelerators.
— Astrophysics: Analyzing high-energy phenomena, such as cosmic rays.
