The graph in Figure 38.34 shows the stopping potential as a function of the frequency of the incident light falling on a metal surface,(a) Find the photoelectric work function for this metal.(b) What value of Planck's constant does the graph yield?(c) Why does the graph not extend below the x-axis?(d) If a different metal were used, what characteristics of the graph would you expect to be the same and which ones to bedifferent?
