Stopping potential versus incident light frequency for two metals.
Stopping potential versus incident light frequency for two metals.
An experiment is conducted to determine the photoelectric properties of two different metallic surfaces, Metal 1 and Metal 2. The stopping potential \(V_s\) is measured as a function of the frequency \(f\) of the incident light, and the data are shown in the graph provided. Monochromatic light of a single frequency \(f_A\), where \(f_A > f_2 > f_1\), is shone onto both metals. Which of the following correctly ranks the work functions \(\Phi_1\) and \(\Phi_2\) of the metals and the maximum kinetic energies \(K_1\) and \(K_2\) of the photoelectrons emitted from each surface?
