I need to find the equation for the question.

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.

(I think the original thread was posted in the wrong section!)

The complete solution was deleted (it's not allowed). So if you didn't see it:

(a) ------------------------------

The waves must interfer constructively only over a region.

(b) ------------------------------

You have forgotten some time-dependent terms.

(c) ------------------------------

The correct solution of (b) contains a periodic time function. It's period is the answer
