The table below lists the stopping potential as a function of wavelength in a photoelectric effect experiment. Determine quantities to plot that should yield a straight line. Make your plot, establish a best-fit line, and use your line to determine(a) an experimental value for Planck?s constant (b) the work function of the material comprising the photocathode.(c) Use Table 34.1 to identify the material.
