In this problem you need to determine the work function of an unknown metal. You will need to collect data on the energy of your electrons for different wavelength of light and then use this to find the work function of your metal. Making a graph of KE of the electrons in eV vs. frequency in Hz is the best way to get the work function of your metal.
