Answer to Question #141983 in Quantum Mechanics for Khloe

Question

Define the following: (i) Thermionic emission, (ii) Photoelectric emission, (iii) Stopping potential

Answer 1

Thermionic emission is defined as the electron emission by giving high amount of thermal energy to the metal.

Photoelectric emission is defined as the emission of electrons from a metal plate when illuminated by light on alkali metals.

The stopping potential is defined as the potential difference applied between the plates to stop electrons from moving between alkali metal plates
