The finite potential well (also known as the finite square well) is a concept from quantum mechanics. It is an extension of the infinite potential well, in which a particle is confined to a "box", but one which has finite potential "walls". Unlike the infinite potential well, there is a probability associated with the particle being found outside the box. The quantum mechanical interpretation is unlike the classical interpretation, where if the total energy of the particle is less than the potent… WebJun 16, 2024 · Griffiths claims that N is related to n and l, but in a quite complicated way for the infinite spherical well case (that's why he prefer to distinguish between N and n ).
