Maximum kinetic energy vs. frequency of incident light.
Maximum kinetic energy vs. frequency of incident light.
A student shines monochromatic light of various frequencies \(f\) onto a metal plate in an evacuated tube and measures the maximum kinetic energy \(K_{\max}\) of the emitted photoelectrons. The graph shows the measured maximum kinetic energy as a function of the light frequency. Based on the graph, what is the work function of the metal plate?
