Energy and momentum eigenfunctions

  1. Mar 26, 2007 #1
    just a general and quick question because I'm making a formula sheet for my test tomorrow:

    What is the energy eigenfunction for a free particle and what is the momentum eigenfunction for a particle in a box?

    Why are you asking?!? If you're taking a QM class, surely you've covered these things in class and they are in your textbook!

    i skipped QM and went into quantum theory so i never went over this. this isnt talked about in my book. all i need to know is the energy eigenfuction for a free particle please? Oh and momentum eigenvalues for a particle in a box?

    That's an interesting Q though.

    What are the momentum eigenfunctions of a particle in a box? The FT of the waves between the walls must look a bit weird.
