The results of spectra obtained by Balmer were expressed in 1896 by:
Correct answer: C. Rydberg
- A. Newton
- B. Bohr
- C. Rydberg
- D. Planck
Explanation
In 1896, the results of spectra obtained by Balmer were expressed by Johannes Rydberg. He developed the Rydberg formula, which extended the work of Balmer and provided a more general formula for spectral lines in many chemical elements.

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.
