In a photoelectric effect experiment, you shine light of wavelength 420 nm on a piece of sodium metal and measure the stopping potential to be 0.65 V. You then use a different spectral line with a wavelength of 310 nm and measure the stopping potential to be 1.69 V. Using those two data points, the speed of light and the elemental electric charge, find the work function of sodium and a value for Plank’s constant.
