Chapter 38, Problem 38.31(choose chapter or problem)
When a certain photoelectric surface is illuminated with light of different wavelengths, the following stopping potentials are observed: Plot the stopping potential on the vertical axis against the frequency of the light on the horizontal axis. Determine (a) the threshold frequency; (b) the threshold wavelength; (c) the photoelectric work function of the material (in electron volts); (d) the value of Plancks constant h (assuming that the value of e is known).
