In the production of X-rays _ source is used.

Correct answer: B. DC

  • A. AC
  • B. DC
  • C. Both A and B
  • D. None of the above

Explanation

A DC X-ray machine uses direct electric current to power the X-ray tube head. These constant potential (DC) machines neither change direction nor the intensity making it a steady supply of power. This facilitates the production of smooth and consistent X-rays.With an alternating current AC generator, the voltage across the tube goes from zero up to the maximum kVp, then back to zero. This produces X-ray photons of varying energies.

About Atomic Spectra

Atoms emit or absorb light at specific wavelengths because electrons occupy quantized energy levels and change levels by absorbing or releasing photons. The topic covers emission and absorption spectra, spectral series, hydrogen’s line spectrum, energy-level transitions, and the relation between wavelength, frequency and photon energy.
