If wave number is RH/9, the corresponding series is:
Correct answer: C. Paschen Series
- A. Lyman series
- B. Balmer series
- C. Paschen Series
- D. Brackett series
Explanation
A wavenumber of Rh over 9 means the electron is ending on the third energy level. Transitions that finish at this level are part of the Paschen series.

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.
