    1. The problem statement, all variables and given/known data

    2. Relevant equations

    I need to find the equation for the question.

    3. The attempt at a solution

    a)

    A bunch of waves/wave functions, that have phases/amplitudes that interfere constructively.

    b)

    |Y(x,t)|Squared = Co(/)0 + C1(/)1 Squared ???

    c)

    No idea

    d)
    i)

    A graph that slopes down, (qe) to then up to a peak, (Difference between each point is Ea) then finally back down to q.
    ii)

    Down then up then to a straight like across.






    I'd also like to know how to work out the time taken to travel to an adjacent potential well assuming Y(x,t=0) = Co(/)0 + C1(/)1
    I think (/)0 and (/)1 are the lowest eigenstates and C0 and C1 are just coefficients.
