Sorry for the late reply, I was busy with the exam. Sorry again because my question is not clear, so basically my question is: Usually the graph of photoelectric current against voltage will be looks like this ( Picture 1) Is it possible that we can get a graph looks like this ? (picture 2)

Sorry for the late reply, Peter. Thanks for the explanation. Your explanation bring me to a higher level of understanding the resonance. But I am curious for that -- how does them looks like in a tube? By the way thanks again.

Thanks, ZapperZ. But what about the concept of "drift velocity of the photoelectron will affect the current" idea? And another small question which is out of topic: My friend asked me whether it is possible to reach a saturation current even when a reverse voltage applied or at 0 voltage? Then...

From the post https://www.physicsforums.com/threads/photoelectric-effect-saturation-current.720506/ and http://www.thephysicsforum.com/quantum-physics/3921-photoelectric-current-dependence-potential-difference.html I have some idea on why does a higher potential different will not increase the...

Question Hi, I am new here. I actually don't understand the pattern of the standing waves if there are situation like "If we excite the tube at a different, non-resonant frequency", will there are always node at the water surface and antinode at the open end? Secondly, if it is, then, at...
