Diffraction data refers to the information obtained from the phenomenon of diffraction. Diffraction occurs when a wave, such as light, X-rays, or electrons, encounters an obstacle or aperture that has dimensions comparable to its wavelength. The wave then bends or spreads out, creating an interference pattern of bright and dark fringes. This pattern is what constitutes the diffraction data.

The specific characteristics of the diffraction pattern, such as the spacing and intensity of the fringes, are directly related to the size, shape, and arrangement of the diffracting object or the scattering entities. By analyzing these patterns, scientists can deduce valuable information about the material or structure under investigation. For instance, in X-ray diffraction, the diffraction data from crystalline materials provides insights into their atomic arrangement, crystal structure, and lattice parameters. This technique is fundamental in fields like crystallography, materials science, and chemistry for identifying unknown substances and understanding their properties.

In optics, diffraction data from light passing through slits or gratings can be used to determine the wavelength of the light or the dimensions of the slits. Electron diffraction data is crucial in microscopy for characterizing the structure of very small samples. The collection and interpretation of diffraction data are therefore essential for a wide range of scientific and technological applications, enabling detailed structural analysis at the atomic and molecular level.
