It doesn't matter. But if your potential goes to some finite value at , it's conventional and convenient to set that value to zero. That's what we do for the finite square well. For the infinite square well this is impossible, because the potential is infinite outside of a small region. So we may as well set the potential within that small ...

WebIf you really want to deal with an infinite potential well, then you should set b = L and enforce the boundary condition ψ ( b) = 0 . In this case it also makes sense to start shooting at x = − b , with ψ ( − b) = 0 and ψ ′ ( b) nonzero. Hopefully this helps.

WebApr 10, 2024 · According to Weyl, “‘inexhaustibility’ is essential to the infinite”. However, he distinguishes two kinds of inexhaustible, or merely potential, domains: those that are “extensionally determinate” and those that are not. This article clarifies Weyl's distinction and explains its enduring logical and philosophical significance. Webbelow left shows the 13 allowed values of 2b π for a finite well for which β0 = 20.

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".
