1. The problem statement, all variables and given/known data http://img29.imageshack.us/img29/5236/phst.jpg [Broken] 2. Relevant equations http://img25.imageshack.us/img25/8815/11203939.jpg [Broken] 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.
