To calculate the threshold frequency of the metal we use the formula,
Also,
Here, E is the energy of electron per atom, h is plank constant.
Given, binding energy of electron or for one electron,, here N is the Avogadro constant and its value is , so and plank constant,
Substituting these values in above relation we get,
.
Thus, the threshold frequency of the metal is .
