Using the data generated below, 1. Plot a graph which will allow you to determine the threshold frequency and work function of the metal. 2. Using the graph, determine the threshold frequency (in Hz) and the work function (in el) of the unknown metal. 3. Using the work functions provided, identify the unknown metal.
