Photoelectric effect

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
