We’re being asked what is the minimum energy needed to eject an electron from a molybdenum metal. The minimum frequency of radiation that must be absorbed by the metal is 1.09x1015 s-1.

We can calculate the minimum energy from the minimum frequency absorbed using the equation:

E=hν

 E = energy = J
▪ h = Planck's constant = 6.626x10-34 Js
 ν = frequency = Hz or s-1
