Which of the following leads to Generation of X- Rays?

X rays are produced when Fast-moving electrons from the cathode strike the anode and are decelerated in the orbital shells of the anode. The loss of kinetic energy of the electron is released as X-ray Photon, Called as Bremsstrahlung Radiation/Braking Radiation. Penetrating power of X-rays increases with increasing energy, which is propoional totheincreasing frequencyand decreasing wavelength.
