[SOLVED] A question about Photoelectric Effect According to my teacher "photoelectric current is independent of frequency but dependent on intensity". This statement seems to conflict the following exercise: "In an experiment to investigate the photoelectric effect, monochromatic light is incident on a metal surface. The photoelectric current and the maximum kinetic energy of the photoelectrons are measured. Which one of the following correctly shows the change, if any, in the photoelectric current and in the maximum kinetic energy of the photoelectrons when light of the same intensity but higher frequency is incident on the same metal surface?" A. Photoelectric current is the same Maximum kinetic energy increases B. Photoelectric current decreases Maximum kinetic energy increases The solution is B. Hence, my teacher's statement is ambiguous. Clearly, photoelectric current is NOT independent of the frequency as an increase in frequency has decreased the current. Hence, i think I don't understand the statement of independence. Please, help me!
