Whenever a material absorbs electromagnetic radiation then it starts I'm eating electrons and that is the reason or phenomenon of Photoelectric effect. You will be glad to know physicist Albert Einstein was the first person to discover it and receive a Nobel prize for this explanation. Some applications of Photoelectric effect are the photoelectric cells which are used for detecting light using a vacuum tube and containing a cathode in it. Other applications are in camera tubes or for studying nuclear processes or for some theoretical information regarding electrons in atoms.

The correct answer is - Television camera.
The photoelectric effect is the phenomenon of emission of electrons or charged electromagnetic particles from the surface of a material when electromagnetic radiation is absorbed by the surface.
In a television camera, the electrons or electromagnetic particles are emitted due to the photoelectric effect. The resulting electrical current is then processed in order to convey the information. It is later recreated on a Cathode ray tube (CRT) or other forms of display.
