# Work function watch

1. I've been asked tcalcukate the work function of lithium, and I've been given the threshold frequency (5.5x10^14Hz). I know that the threshold frequency is the frequency of the energy required to remove the electron, but how do I translate this into work function?

Work function(Eo) is equal to Planck's constant(h) times the threshold frequently(fo).

So Eo=hfo.
