When an electron jumps from n = 5 to n = 2 having wave number equal to 2.3 x 16 m-1. In which spectral series will it fall?
Correct answer: B. Balmer
- A. Lyman
- B. Balmer
- C. Visible
- D. Infrared
Explanation
Correct option is B. The Balmer series is the name given to a series of spectral emission lines of the hydrogen atom that result from electron transitions from higher levels down to the energy level with principal quantum number 2.

About Spectrum of Hydrogen
The hydrogen spectrum consists of discrete emission lines produced when electrons fall between quantised energy levels and release photons. Questions use the Rydberg equation, photon energy and wavelength, and identify the Lyman, Balmer, Paschen, Brackett and Pfund series, which differ from continuous spectra.
