WebSee how light knocks electrons off a metal target, and recreate the experiment that spawned the field of quantum mechanics. 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.

Its characteristics are: (i) The momentum of a photon is given by p = $\frac { {\rm {h}}} {\lambda }$. (ii) The rest mass of photon is zero. Hence, a photon cannot be at rest. 2. The electrons obtained from the photoelectric effects are called photoelectrons. o\u0027rourke beto real name
