Homework Help: Normalization Constant A

  1. Mar 27, 2007 #1
    1. The problem statement, all variables and given/known data

    The wave function of a particle is Y(x,t) = A e^-kx*e^-iwt for x greater than or equal too 0, and it is zero everywhere else. What is the numerical value of the normalization constant A for k=5.55 1/nm and w =7.19 1/ps?

    2. Relevant equations

    intergral Y^2=1

    3. The attempt at a solution

    I tried setting x=0 so my equation becomes Y(0,t)= A*e^-iwt
    I then squared the equation A^2*intergral of e^2(-iwt)

    I don't know where to go from here can someone help?

    More correctly, it's integral of Y times complex conjugate Y. So the time dependence drops out. The remaining x integral is not that challenging, is it?
