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

Correct answer: A. Appears as photon

  • A. Appears as photon
  • B. Appears as an electron- positron pair
  • C. Appears as its K.E.
  • D. It vanishes

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.

About Photons and the Particle Model of Light

The particle model treats light as photons with energy E equals hf and momentum related to wavelength. Questions involve the photoelectric effect, work function, threshold frequency, stopping potential and photon energy, while distinguishing particle behaviour from the wave description of interference and diffraction.
