Where does the energy lost by fast-moving electrons go?

Explanation

When a fast-moving electron loses energy, it can emit a photon. This phenomenon is known as bremsstrahlung radiation or braking radiation.When a fast electron approaches a positively charged nucleus or interacts with a strong electromagnetic field, it experiences a deceleration or change in direction due to the electrostatic forces involved. As a result, the electron's kinetic energy decreases.According to the conservation of energy, the lost kinetic energy of the electron must be conserved. This lost energy is converted into electromagnetic radiation, specifically a photon. The emitted photon carries away the energy that the electron has lost.The energy of the emitted photon depends on the magnitude of the electron's energy loss.
