Splitting of spectral lines when atom is subjected to magnetic field is called _______________?
Correct answer: A. Zeemans effect
- A. Zeemans effect
- B. Starks effect
- C. Photo electric effect
- D. Compton effect
Explanation
The splitting of spectral lines in the presence of a magnetic field is called the Zeeman effect. The Stark effect is splitting caused by an electric field. Students may choose Stark effect because both effects involve spectral-line splitting, but the question specifies a magnetic field.

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.
