Answers (1)

(a)  Threshold frequency(\nu_0) = The minimum frequency that's required for emission of electrons from a metal surface when electromagnetic radiation falls on the metal surface

b) Stopping potential (V_0)

It is the necessary potential applied externally to prevent the most energetic electron from reaching the endplate.
