Define: i) photoelectric work function ii) electron volt (eV)

Text Solution

Verified by Experts

Photoelectric work function: Work function of a metal surface is the minimum amount of energy required to liberate an electron from the metal surface. Electron Volt (eV): 1eV is the energy acquired by an electron when it is accelerated by applying a potential difference of one volt. `i,e leV=1.6 xx 10^(-19)J`
