In Preskill's notes, John Preskill goes as

If we scatter a photon off of a periodic array of needles , the photon is likely to be scattered in one of a set of preferred directions , where the Bragg scattering condition is satisfied.

and further

These preferred directions depend on the spacing between the needles , so by scattering just one photon , we can already collect some useful information about the spacing.

How can the analogy with Bragg's diffraction help me understand Simon's problem ?
