Probabiltiy density rho(k,t) of k at time t?
A free 1D particle has initial wave function psi(x)=A exp(x^2/4a^2)
What is the probability density rho(k,t) that a wavevector measurement at time t will measure k?
Please see attachment. I am confused on how to find the probability density of the time dependent wavefunction.
Please help since I have an upcoming test. Thanks
