If electronic transitions in the hydrogen atom terminate in the second orbit, the emitted series is known as:
Correct answer: D. Balmer series
- A. Brackett series
- B. Paschen series
- C. Lyman series
- D. Balmer series
- E. Pfund series
Explanation
The Balmer series is a set of spectral lines in the hydrogen emission spectrum corresponding to electron transitions from higher energy levels to the n=2 energy level. These transitions result in the emission of visible light, making the Balmer series one of the most well-known series in atomic spectroscopy.

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.
