... How do we know the atomic scale structure of matter around us? A crystal is a very large number of atoms or molecules arranged in a periodic fashion. It acts like a grating with an extremely large number (~Avagadro’s number) of units that diffract waves coherently. Every crystal has its own “signatu ...
