Consider the semi-finite square well potential shown below where
V(x) = ∞ for x < 0
V(x) = finite constant for 0 ≤ x ≤ L
As we did in class for a symmetric finite square well, sketch the eigenfunctions ψ₁(x) to ψ₃(x) corresponding to the energy eigenvalues E₁ to E₄ (ground through 4th excited state). Make sure your sketch is clearly labeled so that its behavior in the regions x < 0, 0 ≤ x ≤ L, and x > L can be determined.
