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.
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.
