Answer:

What do you mean by electron emission?

Electron emission is defined as a phenomenon of liberation of electron from the surface that is stimulated by temperature elevation, radiation, or by strong electric field.

Explain briefly various methods of electron emission.

Thermionic Emission: In this type, the metal is heated to a sufficient temperature to enable the free electrons to come out of its surface. Field Emission: In this type, a very strong electric field is applied to the metal which pulls the electrons out of the surface due to the attraction of the positive field.
