When electromagnetic radiaiton of wavelength 300 nm falls on the surface of sodium electrons are emitted with a kinetic enegry of 1.68xx10^(5)Jmol^(-) . What is the minimum enegry needed to remove an electorn from sodium? Strategy: The minimum enegry required to remove an electron from target metal is called work function W_(0) of the metal. It can be calculated from Eq., provided we know the energy of the incident photon and kinetic enegry of a single photoelectorn.
