... illustrate the basic ideas of quantum mechanics. More realistic cases involve potentials that are not infinite but finite. The walls in the particle in box problem denote an extremely hard or impenetrable barrier. If we reduce the magnitude of potential, i.e. make the walls bit softer, the strict re ...
