I'm very confused, as there are conflicting sources: Why doesn't photoelectric current increase with frequency of the incident wave?
This states that frequency does not affect current because it does not eject more electrons, it only affects the initial kinetic energy of the electrons, which make sense.
However, I'm looking at this simulation here, which when I change the frequency, current is changed: https://phet.colorado.edu/en/simulation/photoelectric
Which one is correct?
