We’re being asked to determine the shortest frequency of light required to remove an electron from a sample of metal. The threshold frequency of the metal is 3.14x103 kJ/mol.

Recall that work function or threshold frequency of the metal is the minimum energy required to remove an electron from the metal.


Therefore, we can calculate the shortest frequency of light required from the threshold frequency or threshold energy.

Given:

ΔE = 3.14x103 kJ/mol
