Here, a finite, rectangular, one-dimensional potential energy function (potential for short) \( W_{\text{pot}}(x) \) was sketched as a function of space \(x\). The potential has the length \( L \).

  • Inside the potential well, that is between \( -L/2 \) and \( L/2 \), a particle has no potential energy.
  • Outside the potential well, the particle has a finite potential energy \(V_0\).
