The idea is that, due to the small wavelength of X-rays, atoms can serve as a diffraction grid - causing diffraction patterns. (If you don't know about diffraction, I suggest you search in the questions for "diffraction", or ask a separate question for diffraction.) Crystals are good for this, because of their regular structure.
No, x-ray diffraction and crystallography are not synonymous terms in the field of material analysis. X-ray diffraction is a technique used to study the atomic and molecular structure of materials, while crystallography is the broader scientific study of crystals and their structures, which can include various methods beyond just x-ray diffraction.
To determine the crystal structure from X-ray diffraction (XRD) data, scientists analyze the diffraction pattern produced when X-rays interact with the crystal lattice. By comparing the diffraction pattern to known crystal structures and using mathematical techniques, such as Fourier analysis and structure factor calculations, they can determine the arrangement of atoms in the crystal lattice.
To calculate interplanar spacing in a crystal lattice structure, you can use Bragg's Law, which relates the angle of diffraction to the spacing between crystal planes. This formula is given by: n 2d sin(), where n is the order of the diffraction peak, is the wavelength of the X-ray used, d is the interplanar spacing, and is the angle of diffraction. By rearranging this formula, you can solve for the interplanar spacing (d) by measuring the angle of diffraction and the wavelength of the X-ray.
In X-ray diffraction analysis, the angle 2theta is significant because it helps determine the spacing between crystal lattice planes in a material. This information is crucial for identifying the crystal structure of a substance, which is important in various scientific fields such as materials science and chemistry.
Max von Laue did not invent anything, but he was a German physicist who won the Nobel Prize in Physics in 1914 for his discovery of the diffraction of X-rays by crystals. This discovery laid the foundation for the field of X-ray crystallography, which is used to study the structure of crystals and molecules.
X-ray diffraction is a common method for determining crystal structure.

X-ray diffraction uses X-rays to study the atomic structure of materials, while neutron diffraction uses neutrons. Neutron diffraction is particularly useful for studying light elements like hydrogen because neutrons interact strongly with them, while X-ray diffraction is better for heavy elements. Neutron diffraction also provides information about magnetic structures due to the neutron's magnetic moment.

Although many people would not fully understand this electron diffraction gives you only one plane. X-Ray diffraction will give you a scattering of all the planes in one measurement.

Francis Crick and James Watson used existing data and research, particularly X-ray diffraction images of DNA by Rosalind Franklin, to build models of the DNA molecule. They proposed the double helix structure of DNA in 1953, which revolutionized our understanding of genetics and heredity. Their model explained how genetic information is stored and replicated in living organisms.
