Lecture Details

The Finite Square Well Potential, case E ≤ V₀
In graphing the expressions for each equation, we can this famous graph in quantum mechanics showing the discrete energy values for a finite square well potential.

Note that the number of solutions depend on the size of R, which in turn depends on the depth V₀ and the width a of the well.

Also, in the limiting case V₀→∞, the circles radius R becomes infinite we recover the energy expression for the infinite well.
