WebJan 30, 2024 · The Photoelectric Effect. Light incident on a metal plate may cause electrons to break loose from the plate surface (Fig. 1). This interaction between light and electrons is called the photoelectric effect. The photoelectric effect provided the first conclusive evidence that beams of light was made of quantized particles. Webphotoelectric effect, Phenomenon in which charged particles are released from a material when it absorbs radiant energy ( see radiation ). It is often thought of as the ejection of electrons from the surface of a metal plate when visible light falls on it. It can also occur if the radiation is in the wavelength range of ultraviolet radiation, X ...

In general, the photoelectric effect is the emission of electrons when light is incident on metallic objects. It is broadly classified into two types: the internal photoelectric effect and the external photoelectric effect. The major components of this effect are Planck’s equation, threshold energy, and photoelectric equation.
