The Finite Square Well Potential, case E ≥ V₀

We venture back again to the fundamental question of whether the wave solutions to the Schrödinger are physical. We sketch the probabilities densities |Ψ|² and again see that they have no physical meaning - it is absurd to say that a particle can be found in a region with probability of say 4.
