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.

You can do it for each well separately right?
It's just a sketch - you you don't need to be exact - so just sum what you get for each one apart.
