The characteristic X-ray spectrum is due to:
Correct answer: C. The bombardment of target material by electrons
- A. The absorption of neutrons by target material
- B. The bombardment of target material by protons
- C. The bombardment of target material by electrons
- D. The bombardment of target material by alpha particles
Explanation
The characteristic x-rays are obtained due to the transition of electron from inner orbits of the atoms, so the target is bombarded by electrons.

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.
