Stopping potential versus frequency for Metal 1 and Metal 2.
An experiment measures the stopping potential \(V_s\) as a function of light frequency \(f\) for two different metallic cathodes, Metal 1 and Metal 2. The resulting data are plotted in the graph shown. Metal 2 is known to have a larger work function than Metal 1 (\(\Phi_2 > \Phi_1\)). Which of the following claims correctly explains the relationship between the graph features and the physical properties of the metals?
