FIGURE Q38.5 is the current-versus-potential-difference graph for a photoelectric-effect experiment with an unknown metal. If classical physics provided the correct description of the photoelectric effect, how would the graph look if:

a. The light was replaced by an equally intense light with a shorter wavelength? Draw it.b. The metal was replaced by a different metal with a smaller work function? Draw it.
