These data are obtained for photoelectric stopping potentials using light of four different wavelengths.
(a) Plot a graph of the stopping potential versus the reciprocal of the wavelength.
(b) Read the values of the work function and threshold wavelength for the metal used directly from the graph.
(c) What is the slope of the graph? Compare the slope with the expected value (calculated from fundamental constants).
