SUMMARY
The discussion clarifies the difference in potential energy settings between the infinite square well and the finite square well in quantum mechanics. In Griffiths' treatment, the infinite square well is defined with a zero potential within a confined region, while the finite square well has a base potential set at a negative value of -V_0, where V_0 is a positive real number. This distinction is made because the infinite square well has infinite potential outside its boundaries, making it impractical to set a zero reference point outside the well. Conversely, the finite square well allows for a finite potential at infinity, justifying the zero reference point.
