For a certain photo-emissive metal surface, the threshold frequency corresponding to the stopping potential plot gives a work function value. If the intersection of the stopping potential line on the frequency axis identifies a threshold frequency of 5 × 1014 Hz, what is the work function of the surface? (Take h = 4.14 × 10-15 eV·s)
