1. The problem statement, all variables and given/known data find the wavefunction of a particle in a potential V(x)= 0, |x|< a V, |x|< b (V>0) (Infinity), |x|>=b ground state energy 0<=E<=V 2. Relevant equations 3. The attempt at a solution i know the wavefunction has to be equal to zero at the infinite barrier so when i use that as my boundary condition for the V potential region i just get that the particle has zero probability of being in this region at all, leaving only the zero potential region for it to lie within. but i cant understand why the infinite barrier should have this effect, if it werent for this barrier the particle would be able to reach this higher energy region. can any1 help me with an explanation of this effect, or if it is not the case point out where i'm going wrong?
