photoelectron

A photoelectron is an electron that is emitted from an atom or molecule when it absorbs light energy. When light hits a material, such as a metal, the energy can transfer to electrons within it. If the energy is enough to overcome the material’s binding forces, the electron escapes into the surrounding space. This process is called the photoelectric effect. Photoelectrons are important in understanding how light interacts with matter, and they are used in technologies like solar panels, cameras, and scientific instruments to analyze the composition and properties of materials.
