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?

so i've went there already, and coundt find them, which is why i'm asking on this forum. maybe i just cant spot them out?

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.
