X-rays are produced from:
Correct answer: B. Inner shell
- A. Both inner and outer shell
- B. Inner shell
- C. None of these
- D. Outer shell
Explanation
X-rays are high-frequency electromagnetic radiations that are produced when accelerated electrons strike the target material and cause the inner-shell electrons to be ejected. The valence shell electrons then leave their positions to occupy the vacant space in the inner shells, thereby releasing an X-ray photon.

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.
