Question

difference between workfunction and threshold energy? ​

Answer 1

Answer:

The minimum energy needed to eject an electron from a metal is known as the work function of the metal. ... A photon having an energy at least equal to the work function can eject electron from the metal, frequency of such a photon whose energy is just equal to the work function is called threshold frequency.
