Although WKB potential only applies to smoothly varying potentials,<ref name=":2" /> in the examples where rigid walls produce infinities for potential, the WKB approximation can still be used to approximate wavefunctions in regions of smoothly varying potentials. Since the rigid walls have highly discontinuous potential, the connection condition cannot be used at these points and the the results obtained can also differ from that of the above treatment.<ref name=":1" />
