Photocurrent and frequency of incident light

  1. May 15, 2013 #1
    Why is photocurrent in the photoelectric effect independent of the incident frequency of light after the threshold frequency? If more frequency means more kinetic energy of electrons, then doesn't that mean that there should be more electrons passing a cross-section of the metal tube per second i.e more current?

    So decreasing the wavelength does increase the current. I thought it had no effect.

    I will read that link when I have the time.

    Thanks a lot Jano L.!
