Photon explained
Webphotoelectric effect, phenomenon in which electrically charged particles are released from or within a material when it absorbs electromagnetic radiation. The effect is often defined as the ejection of electrons from a metal plate when light falls on it. In a broader definition, the radiant energy may be infrared, visible, or ultraviolet light, X-rays, or gamma rays; the … WebThe remainder goes into the ejected electron’s kinetic energy. In equation form, this is given by. K E e = h f − B E, 21.6. where K E e is the maximum kinetic energy of the ejected electron, h f is the photon’s energy, and BE is the binding energy of …
