Work function, ϕ of a metal is defined as the minimum energy required by an electron to escape from the metal surface. Mathematically, ϕ = f_{0}h, where ‘h’ is the Plank’s constant and its value is 6.63 × 10^{-34} J s, f_{0} is the threshold frequency at which the electron just ejects from the metal.
