Calculating constants in mixed state of first two energy levels (infinite Q Well)

  1. Apr 21, 2012 #1
    1. The problem statement, all variables and given/known data
    See attachment

    2. Relevant equations
    for an infinitely deep q well of width L
    [itex]\psi(x)=\sqrt{\frac{2}{L}}Sin\frac{4\pi x}{L}[/itex]

    3. The attempt at a solution
    Taking the inner product;




    from the second part of the question 3a=b and thus a=.25 b=.75

    I kind of went out on a limb with this and I'm not sure if its correct. It seems very little work for the available marks and I'm just not sure if the second part is ok?
