A one-dimensional potential well of a certain length with infinitely high potential walls. This means: A particle inside the potential well would need infinite energy to get out.

The particle (e.g. an electron) inside the well can occupy certain states, described by the wave functions $$\psi_1$$, $$\psi_2$$, $$\psi_3$$ and so on.
