 P: 59 Wave functions of a Kronig-Penny model with the limit (Uo →∞) are considered in this question. The wave functions for k=0, k=1/2, k=$\pi$, k=2$\pi$ in the lowest energy band are sketched. I don't quite understand how these were sketched. I have attached the graphs on here, could anyone please explain? Thanks. Attached Thumbnails
