The shortest wavelength of continuous X-rays emitted from an X-rays tube depends on the
Correct answer: D. atomic number of the target material
- A. current in the tube
- B. nature of the gas in the tube
- C. voltage applied to the tube
- D. atomic number of the target material
Explanation
D is the right option Here's why: The shortest wavelength of continuous X-rays emitted from an X-ray tube depends on the atomic number of the target material. This is because the characteristic X-rays emitted from the target material have wavelengths determined by the electronic transitions within the atoms of the material.

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.
