What is the phenomenon called when the polarization of light rotates as it passes through certain optically active substances placed in a magnetic field parallel to the direction of light propagation?
A. Zeeman effect
B. Faraday effect✓ Correct Answer
C. Stark effect
D. Raman effect
💡 Solution & Explanation
The Faraday effect is a magneto-optical phenomenon where the plane of polarization of light rotates when passing through an optically transparent substance subjected to a magnetic field parallel to the propagation vector. This interaction demonstrates a fundamental coupling between light and magnetic fields.
