Light of constant intensity but varying wavelength was used to illuminate the cathode in a photoelectric-effect experiment.
Question:
Light of constant intensity but varying wavelength was used to illuminate the cathode in a photoelectric-effect experiment. The graph of Figure P28.54 shows how the stopping potential depended on the frequency of the light. What is the work function, in \(\mathrm{eV}\), of the cathode?
