Now we switch metals to one with a larger work function, and we again plot the maximum kinetic energy of the emitted electrons as a function of the frequency of the incident light. Which of the following graphs do we get? The original graph is shown in red, as a reference, in each case?

1. Graph 1 - the same as before
2. Graph 2 - same slope, but shifted to the right
3. Graph 3 - same slope, but shifted to the left
4. Graph 4 - same x-intercept; different y-intercept, larger slope
5. Graph 5 - same x-intercept, different y-intercept, smaller slope
6. Graph 6 - different slope, x-intercept, and y-intercept
