It seems like a very common model that is taught in schools for crystal diffraction is that there is an incident plane wave of light on a crystal lattice, and each atom in the lattice scatters the light, and the light interferes.
But it seems like the scattering part itself isn't diffraction. For example, this wikipedia page for Thomson scattering says that it's responsible for x ray crystallography, but the word 'diffraction' doesn't appear once on the page. In that page, they present the scattering as the usual dipole radiation thing, which is not diffraction, right?
So is diffraction actually present here or is it a misnomer? It seems like it could be, with the x-rays 'bending' around the atoms, but it seems like the dipole radiation takes care of that instead.
