Photoelectric effect refers to the emission of electrons from a metalwhen light is shining on it. In order for the electrons to be liberated from the metal, the frequency of the...

The photoelectric effect is a basic physical phenomenon that not only has a variety of practical current-day applications, but has also inspired a whole new field of science.

A metal contains many mobile electrons. These electrons can be excited when provided with energy. And, if the energy is high enough, the electrons can be excited out ...
