... Schrödinger equation because we already know that photons are waves described by some exp (ik·r – ωt) with ω = 2πν With that, we also know that the boundary conditions imposed by the finite crystal will only allow wave vectors that fit into the crystal and form standing waves. All we have to do then ...
