  • Quanutm Mechanics and the conservation of energy?

    I am looking at the basics of Quantum Mechanics and am trying to understand part of the issue regarding Einstein's equation for calculating Ek (Kinetic Energy).

    Ek = hf - (work function) = h (f-fx)

    *fx is the threshhold frequency - sorry, can't do subscripts

    I understand that it takes the amount of energy fx in order to dislodge the electron.

    This equation, however, seems to lose energy. What happens to the fx energy if the Ek is hf - hfx? Or perhaps the better question is: how is that E tracked/accounted for? It is my understanding that when said metal "recovers" the dislodged electron, fx amount of energy is released (as light?), correct?

  • My Yahoo Answers page suddenly changed format and I don't like it. How can I revert to the old style?

    The layout I had up until last night was far more readable for me. I find this new layout awkward and less informative. Is there a way for an individual to return to the old format?
