The Work Function of Metal.
The minimum energy required to remove an electron from the metal surface is called The Work Function of Metal. This is defined here in the context ofphotoelectric effect. The energy remove an electron from a solid to a point in the vacuum immediately outside the solid surface.
"Ans: A. Work function of a metal
The minimum energy required or needed to remove an electron from the surface of the metal is called the Work Function of a Metal. This can be defined with photoelectric effect. The energy or the work function removes an electron from a solid to a point in the vacuum, immediately outside the solid surface. It is depending upon the metal characteristics. An electron can gain energy by keeping interaction with light particles called photon. So, the energy needed to eject an electron from the surface of metal is called work function of a metal."
