Photoelectric effect

  1. Nov 18, 2005 #1

    from my understanding of the photo electric effect, the minimum workfunction must be met before electrons are emitted prior to that, intensity doesnt play a part. if the frequency is increased to juz above the work function and stays constant there and i increase the intensity shouldnt the current detected be constant and the number of electrons emitted per second is the same?

    If the photons hitting the metal have enough energy to emit photons then the bigger the intensity the bigger the current. Cause more intensity means that more photons are hitting the metal. That means that more electrons are emitted: I = q/t
