Threshold frequency, fo, is the minimum frequency of light needed to get electrons to leave a plate (photoemmission). Every metal has a different thershold frequency. It appears as the x-intercept in the last graph below. Work function E = h fo the minimum energy of light needed to get electrons to leave a plate (photoemmission
