In Balmer series the shortest wavelength radiations have wavelength equal to:

Correct answer: C. 4/RH

  • A. RH/4
  • B. RH/9
  • C. 4/RH
  • D. 9RH

Explanation

In the Balmer series, the shortest wavelength comes from the limiting transition (infinity to 2 ). Using the Rydberg formula lambda=4/RH. So the shortest wavelength in the Balmer series is 4/RH.

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.
