Which one of the following series lies in the ultraviolet region?
Correct answer: C. Lyman
- A. Balmer
- B. Paschan
- C. Lyman
- D. Bracket
Explanation
Provided the figure 19.2 in pg#344 in FTB, Lyman series are the only series that lies in the Ultraviolet region of the line spectrum. While Balmar lies in the visible region of the line spectrum. Paschen,Brackett and Pfund lies in the Infrared region of the line spectrum.

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.
