Answer:
Explanation:
When a beam of electromagnetic radiation, such as light falls upon a metal surface, electrons are emitted. These emitted electrons are called photoelectrons and the phenomenon is called the photo-electric effect. This phenomenon is explained by considering light to be of particle nature and the particles are called photons.
In order to eject electrons, some energy is required i.e. the work function of the metal surface. This energy can only be provided by the particles of light which are known as photons. On the other hand, if light were a wave, electrons must be ejected when the metal surface is exposed to a continuous source for a long period of time.
