Homework Help: Photoelectrons Question.

  1. May 1, 2008 #1
    1. To make it easier I just scanned it


    I am supposed to find how many photoelectrons are ejected per second in the experiment represented by the graph.

    2. See link

    3. Also see link, all of my work so far is there [not all of it, my tutor took other figurings with her, so excuse the lack of lots of writing], I figured since Kinetic energy and potential difference were directly proportional K[max] is 10eV, but as you can see my answer is way off, anyway, any help would be greatly appreciated, and yes, I am female, I write in pink =D.

    Nm, you just have to divide max current since it's C/s by 1.60E-19 C.
