If the series limit wavelength of the Lyman series 920 A0, then that for the Balmer series is:
Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
The series limit of the Lyman series corresponds to the photon emitted when an electron reaches the first energy level from very high levels. For the Balmer series, it corresponds to a photon emitted when an electron falls to the second energy level. Because the second level is higher than the first, the Balmer series limit has a longer wavelength than the Lyman series limit.

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.
