Homework Help: How to find the time-independent (unnormalized) wavefunction

  1. Mar 31, 2014 #1
    1. The problem statement, all variables and given/known data

    How would I find the time-independent (unnormalized) wavefunction given the momentum? I don't know if this can be generalized without giving the momentum in the problem. I want to do this problem myself but I'm stuck.

    The problem states:

    A particle of mass m moves in one dimension (x). It is known that the momentum of the particle is [itex]p_{x}[/itex]=[itex]\hbar[/itex][itex]k_{0}[/itex], where [itex]k_{0}[/itex] is a known constant. What is the time-independent (unnormalized) wavefunction of this particle, [itex]\psi[/itex][itex]_{a}[/itex](x)?

    this is only the first part of the problem. If I get past this I believe I can finish the rest.

    If you have a particle prepared in a position-space state ##\psi(x)##, how would you normally go about finding the momentum of the state?
