1. The problem statement, all variables and given/known data Particle moves in one dimension in the potential shown here. The energy E is shown on the graph and the particle is in its ground state. Sketch ψ(x) 2. Relevant equations ψ''+2m(E-V0)/ħ^2 ψ=0 3. The attempt at a solution For E>V0: The graph of ψ goes toward x axis, ψ and ψ'' have opposite signs. For E<V0: The graph of ψ goes from x axis, ψ and ψ'' have the same signs. The graph must end up going towards the zero on both ends.
