Who is this topic relevant for?

How it works

The photoelectric effect is a process in which light, or electromagnetic radiation, interacts with matter to produce an electric current. When light hits a metal surface, it can eject electrons from the surface, creating an electric current. This occurs when the energy of the light is sufficient to overcome the binding energy that holds the electrons to the metal. The photoelectric effect is a fundamental concept in physics, demonstrating that light can behave as both a wave and a particle.
