Question

Quizplus · Accepted Answer

The splitting of spectral lines, known as the Zeeman effect, is used to measure the Sun's magnetic field. This is because magnetic fields can cause the energy levels of atoms to split into multiple levels, resulting in a splitting of the spectral lines. By measuring the amount of splitting, scientists can calculate the strength of the magnetic field. The splitting of spectral lines, known as Zeeman splitting, is caused by the interaction between the magnetic field and the spectral line. By studying this splitting, scientists can determine the strength and orientation of the magnetic field.
