photoelectric
Radiation liberates electrons
Photoelectric describes phenomena involving the emission of electrons from a surface when light strikes it.
The photoelectric effect—electrons ejected by photons—was central to early quantum theory.
Photoelectric cells convert light into electrical signals, enabling devices from solar panels to automatic doors: The photoelectric sensor triggered the streetlights at dusk.
