can an amorphous substance be used to determine the substance's inner structure?
UNANSWERABLE
determination of crystal structure using x ray diffraction X-ray crystallography what is the primary use of the above method? In its first decades of use, this method determined the size of atoms, the lengths and types of chemical bonds, and the atomic-scale differences among various materials, especially minerals and alloys. what are the materials and equipment needed to carry out this method?

X-ray crystallography [SEP] Advantages of a crystal
In principle, an atomic structure could be determined from applying X-ray scattering to non-crystalline samples, even to a single molecule. However, crystals offer a much stronger signal due to their periodicity. A crystalline sample is by definition periodic; a crystal is composed of many unit cells repeated indefinitely in three independent directions. Such periodic systems have a Fourier transform that is concentrated at periodically repeating points in reciprocal space known as "Bragg peaks"; the Bragg peaks correspond to the reflection spots observed in the diffraction image. Since the amplitude at these reflections grows linearly with the number "N" of scatterers, the observed "intensity" of these spots should grow quadratically, like "N".
