Homework Help: Form of a Plane wave?

  1. Apr 8, 2007 #1
    1. The problem statement, all variables and given/known data
    The psi function for a free particle is e^(i(kx-wt))

    But does it satisfy the SE?

    2. Relevant equations

    3. The attempt at a solution
    I get w=hk^2/(4(pi)m) when plugged into the SE

    but does w really equal that?

    E=hbar w = hbar^2 k^2 / 2m

    There's one hbar too many in there, no?
