In about 1916, R. A. Millikan found the following stoppingpotential data for lithium in his photoelectric experiments: Wavelength (nm) 433.9 404.7 365.0 312.5 253.5 Stopping potential (V) 0.55 0.73 1.09 1.67 2.57 Use these data to make a plot like Fig. 38-2 (which is for sodium) and then use the plot to find (a) the Planck constant and (b) the work function for lithium
