Splitting of spectral lines in closely spaced lines in presence of magnetic field is called:
Correct answer: B. Zeeman Effect
- A. Stark Effect
- B. Zeeman Effect
- C. Photoelectric Effect
- D. Compton Effect
Explanation
Explanation: Splitting of spectral lines in closely spaced lines in presence of magnetic field is called Zeeman effect. This option is not correct. Stark effect is the splitting of spectral lines in an electric field, and is caused by the interaction between the electric field and the charged particles in the atom or molecule.This option is also incorrect because photoelectric effect is the phenomenon in which electrons are emitted from a material when light is shown on it. It occurs when photons of light have enough energy to knock electrons out of the material. This option is also incorrect because Compton effect is the scattering of X-rays and gamma rays by matter, which causes a shift in the wavelength of the radiation.

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.
