===== The Prompt =====

**Consider a 3-chain potential well system with separation distance a. Recall the enevelope function for an electron in a potential landscape with N wells can be described with,**

$$
\psi(x)=\sum_{n=1}^{N}A\sin(kna)\phi(x-na)
$$

**Sketch the first three eigenstates for this system in real space.**
