Continuous X-rays (bremsstrahlung)
What is it?
Bremsstrahlung is X-ray radiation produced when fast electrons are accelerated or decelerated in the electric fields of target atoms, producing a continuous spectrum of photon energies.
In simple words
- Electron deceleration produces a continuous X-ray spectrum.
Recommended for Class 12
Full school-level explanation
Bremsstrahlung is X-ray radiation produced when fast electrons are accelerated or decelerated in the electric fields of target atoms, producing a continuous spectrum of photon energies.
Formula / Key Relation
“Bremsstrahlung” means braking radiation. An incoming electron passes near a target nucleus. Its path and velocity change because of the electric interaction. The electron loses some kinetic energy. That energy can be emitted as an X-ray photon. Different electrons lose different amounts of energy. Therefore, a continuous range of X-ray photon energies is produced. Photon energy ≤ electron kinetic energy Maximum possible photon energy: Emax = eV
Remember
- Photon energy ≤ electron kinetic energy
- Emax = eV
