Homework Help: Quantum Mechanics help

  1. Feb 4, 2010 #1

    Does anyone know the cartesian coordinates equations for the 2px and 2py wave functions?


    1. The problem statement, all variables and given/known data
    Quantum Mechanics

    2. Relevant equations

    looking for them

    3. The attempt at a solution

    I figured out that 1s wave function is e^(-sqrt((x^2)+(y^2)))

    Hi whatsupdog11, welcome to PF!:smile:

    The general eigenfunctions for the Hydrogen atom are derived in every introductory QM textbook I can recall seeing. I suggest you study the chapter of your text that covers the Hydrogen atom, and then return if you still have questions.

    The problem is the class does not have a textbook. I have tried looking up the equations on the internet but i can not find any.

    If your professor is offering no textbook, I would recommending heading over to your library and pulling out a book or two. DJ Griffiths Introduction to Quantum Mechanics is a pretty good book for beginning quantum mechanics. If your library doesn't have it, you can also see R Fitzpatrick's Quantum Mechanics: An Undergraduate Course at this site for a free, electronic copy of his text (you need Adobe Acrobat reader or some other PDF reader).

    I think Griffiths is a better choice than Fitzpatrick, but both are good beginning QM texts.

    Here's a list:

    I assume they're correct.
