    Can the Momentum of an Electron Be Determined from Its Wavefunction?

    wavefunction/momentum confusion Homework Statement Given a wavefunction \Psi=Asin(cx) of an electron can i find it's momentum? Homework Equations Thats what i don't know. The Attempt at a Solution Wave function squared is the probability if finding the particle. So I'm given the...

    Undergrad How to switch between momentum/real space

    I'm a bit confused about using momentum and real space and switching between them and some crap about Fourier series. Can someone provide some links to where i can study these. Please keep in mind that i am new to quantum physics.

    Momentum Real Space - Possible Values & Probabilities

    Homework Statement Suppose at t = 0, a system is in a state given by the wavefunction, \Psi(x,0)=1/\sqrt{a} for |x|<a/2 and \Psi(x,0)=0 otherwise If, at the same instant, the momentum of the particle is measured, what are the possible values that can be found and with what probability...
