## Homework Statement

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)

## Homework Equations

ψ''+2m(E-V0)/ħ^2 ψ=0

## 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.
