In this activity you are provided with some photoelectric data that you need to plot and analyse
Import this data into excel to and create a plot of frequency vs stopping voltage. Determine the work function, cut off frequency and an estimate for planck's constant from your graph.
Plot this second set of data on the same axis
Make comment of on the similarities and differences between the two metals again finding the work function, cut off frequency and an estimate for planck's constant from your graph.
