When electron jump into orbit 1 then series obtained is___________________?
Correct answer: A. Lyman
- A. Lyman
- B. Paschen
- C. Pfund
- D. Brackett
Explanation
When an electron falls to the first orbit, n = 1, the emitted spectral lines belong to the Lyman series. These transitions release ultraviolet radiation. Students may choose b because Paschen is also a hydrogen spectral series, but it ends at n = 3 rather than n = 1.

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.
