1. The problem statement, all variables and given/known data Problem 1. If I had a wavefunction: [tex] \Psi(x,0) = A(\psi_1(x) + \psi_2(x))[/tex] What is the probability of getting E1 or E2 as your energy? Problem 2 You have a wavefunction: [tex] \Psi(x,0) = Ax; 0<= x <= a/2 ; A(a-x); a/2<= x <= a [/tex] What is the probability that an energy measurement would yield E1. 2. Relevant equations Given Up above 3. The attempt at a solution For problem 1, i feel the probabilities should be 1/2 for each of them, but this seems too easy. I also normalized and found Psi(x,t), A = 1/sqrt(2) For problem 2 I'm completely lost There are an infinite amount of energy levels so shouldnt the probability be 0, but then this doesn't make any sense. I feel I'm missing something. Are the probabilities not that easy?
