What is the Zeeman effect?
A) When a light source is moving relative to an observer, the wavelengths of its spectral lines are shifted to longer or shorter wavelengths.
B) When the temperature of a light source is increased, the wavelength of maximum emission decreases.
C) When a light source is located in a magnetic field, the emitted spectral lines are split into two or more components.
D) When light is focused on a metal surface, electrons are ejected from the metal only if the wavelength of the light is shorter than some critical wavelength.

Question

Quizplus · Accepted Answer

The Zeeman effect occurs when a light source is placed in a magnetic field, causing its emitted spectral lines to split into multiple components. This phenomenon is due to the interaction between the magnetic field and the magnetic moments of the electrons in the atoms.
