Solved: In a photoelectric-effect experiment, the stopping
Chapter 38, Problem 38.79(choose chapter or problem)
In a photoelectric-effect experiment, the stopping potential was measured for several different wavelengths of incident light. The data are as follows: Wavelength (nm) Stopping potential (V) 500 0.19 450 0.48 400 0.83 350 1.28 300 1.89 250 2.74 Use an appropriate graph of the data to determine (a) the metal used for the cathode and (b) an experimental value for Plancks constant
