During the production of x-rays, the cathode and anode are enclosed inside an evacuated glass chamber and a high DC voltage of the order of:
Correct answer: D. 50,000 V is maintained
- A. 1,000 V is maintained
- B. 10,000 V is maintained
- C. 25,000 V is maintained
- D. 50,000 V is maintained
Explanation
During the production of X-rays, a high voltage is applied between the cathode and anode in an X-ray tube, but 50000V is commonly used. The high voltage accelerates electrons emitted from the cathode towards the anode, creating a high-energy electron beam.

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.
