Unformatted text preview: Assume that a quantum mechanical system is prepared so that its initial state is given by: Ψ i =Ψ ( x ,0) = 2 5 ψ 1-i 1 5 2 where 1 and 2 are two states which satisfy the time independent Schrödinger equation: ˆ H 1 = E 1 1 and ˆ H 2 = E 2 2 Q3: a) Does the probability density associated with this state depend on time? A. Definitely yes B. It depends (specify below) C. No, because the time exponentials cancel out D. No, because it only contains energy eigenstates E. No, some other reason b) If so, give the first such time. If not, explain why not ©2010 Steve Goldhaber and the Physics Education Group University of Colorado at Boulder...
