Which of the following series of hydrogen spectra lies in the ultraviolet region of the spectrum?
Correct answer: A. Lyman series
- A. Lyman series
- B. Balmer series
- C. Paschen series
- D. Pfund series
Explanation
The series of the hydrogen spectrum that lies in the ultraviolet region is the Lyman series. This series is characterized by the electron transitions from higher energy levels ( n = 2,3,4.... ) to the lowest energy level ( n = 1 ).

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.
