What is Bremsstrahlung?
Advertisements
उत्तर
When a fast-moving electron penetrates and approaches a target nucleus, the interaction between the electron and the nucleus either accelerates or decelerates it which results in a change of path of the electron.
The radiation produced from such decelerating electron is called Bremsstrahlung or braking radiation.
