What did Zeeman's discovery show about light?

  • It is affected by magnetism

  • It is a particle

  • It is a wave

  • It is constant

Answer

Zeeman's discovery revealed that light is affected by magnetism. He observed that when a light source is placed in a magnetic field, the light emitted splits into several components with slightly different wavelengths. This phenomenon, known as the Zeeman effect, demonstrated that light is not simply a wave but also has particle-like properties, as it interacts with magnetic fields in a way that suggests it is composed of charged particles.
