In 1908, George Ellery Hale noticed that the spectral lines from sunspots were split into closely spaced components, and he concluded that the magnetic fields in the sunspots must be very strong. What is the name given to this effect?

Question

Quizplus · Accepted Answer

The splitting of spectral lines observed by George Ellery Hale in sunspots due to strong magnetic fields is known as the Zeeman effect. This phenomenon is a clear demonstration of the interaction between magnetic fields and light, where the presence of a magnetic field causes the energy levels of atoms to split, leading to the observed splitting of spectral lines.
