If ′R ′ is the Rydberg constant for hydrogen, then the wave number of the first line in the Lyman series is:
Correct answer: E. 3R/4
- A. 4RH/3
- B. RH/4
- C. 4/RH
- D. 4/3RH
- E. 3R/4
Explanation
If ′R ′ is the Rydberg constant for hydrogen, then the wave number of the first line in the Lyman series is: 3R/4. As it is a numerical only one option D is correct.

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.
