Which of the following spectra is most typical of the output of an X-ray tube?
Correct answer: A. A
- A. A
- B. B
- C. C
- D. D
Explanation
The graph, shown in option A, comprises of two types of X-rays, labeled in the graph presented below;1. Characteristic X-rays;These X-rays are produced on instances when outer-shell electrons fill a vacancy in the inner shell of an atom, releasing X-rays.2. Bremsstrahlung/Braking Continnuum;This release of X-ray is exclusive to instances where a charged, accelerated particle i.e. Electrons is decelerated, upon striking against a metal surface or any surface. The outcome is the release of electromagnetic radiation, in the form of photons.

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.
