While conducting research into the design of a light sensor, scientists measured the kinetic energy of photoelectrons that had been ejected from an unknown metal surface. The metal was exposed to various frequencies of EMR and the stopping voltage was measured to obtain the kinetic energy of the photoelectrons. The following data was obtained. Determine the work function of the unknown metal. Graph and according to the graph what is the threshold frequency of the unknown metal?
