Which of the following describes the splitting of spectral lines in the presence of an external electric field?
A. Zeeman effect
B. Stark effect✓ Correct Answer
C. Compton effect
D. Photoelectric effect
💡 Solution & Explanation
The Stark effect describes the shifting and splitting of spectral lines of atoms and molecules when subjected to an external electric field. It serves as the electric-field counterpart to the Zeeman effect, which involves magnetic fields. Discovered by Johannes Stark, this phenomenon provides vital insights into quantum mechanics and atomic structure.
