The line spectrum of hydrogen atom contains the spectral Iines in the region of:
Correct answer: D. all of these
- A. ultraviolet
- B. infrared
- C. visible
- D. all of these
Explanation
The line spectrum of a hydrogen atom contains spectral lines in the regions of ultraviolet, infrared, and visible light. This is because the spectral lines in the hydrogen atom's emission spectrum are a result of electron transitions between different energy levels. The ultraviolet lines correspond to higher energy transitions, the visible lines correspond to intermediate energy transitions, and the infrared lines correspond to lower energy transitions. Therefore, the line spectrum of a hydrogen atom includes spectral lines in all regions.

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.
