Problem
For a metal surface, a straight line is obtained when stopping potential V0 is plotted on the y-axis against the frequency ν of incident light on the x-axis. The point where this line meets the frequency axis represents
(a) the work function of the metal
(b) Planck’s constant
(c) the threshold frequency of the metal
(d) the saturation photocurrent
