if two light with different frequency have the same intensity then the PE current is the same. But that doesn't make sense, and some graphs show that if you increase frequency while intensity is constant, the current increases up to a point then drops. A couple of old threads, people mentioned that as you increase frequency if intensity is constant then the current goes down (Less photons).... but don't you have a high probability of a photon succeeding in ejecting an electron? Which one is right? Thank you in advance.
