The concept of diffraction played a crucial role in developing our understanding of wave-particle duality in quantum mechanics.

In 1678, Dutch physicist Christiaan Huygens proposed that light propagates as a wave through a medium, with every point on a wavefront acting as a source of secondary wavelets, expressed as:

Biomolecular structures are analyzed by directing X-rays at samples to create distinctive diffraction patterns. These patterns generate three-dimensional electron density maps, revealing the complex structures of proteins and nucleic acids and providing insights into functional sites and molecular interactions. This technique was crucial in Watson and Crick's discovery of the DNA double helix structure.7

The choice between synchrotron X-ray or neutron sources impacts data quality, influencing resolution, sampling volume, and peak profiles. This precision is important for optimizing piezoelectric ceramics, where controlling particle size and distribution is necessary for achieving high efficiency and quality.

Additionally, it helps calculate thermodynamic parameters like compressibility and thermal expansion, making it crucial for interpreting mineral chemistry and predicting behavior in both research and practical applications.10

This phenomenon creates distinctive patterns through the interference of light waves. When wave crests align, they amplify the wave intensity (constructive interference), resulting in brighter regions. Conversely, when crests and troughs coincide, they cancel each other out (destructive interference), leading to darker areas. This interference pattern is key to many diffraction phenomena and applications.

While Huygens' model accounts for linear and spherical wave propagation, reflection, and refraction, it does not fully explain diffraction effects.2

Energy dispersive diffraction utilizes a polychromatic "white beam" of X-rays to produce diffraction spectra that reveal information about crystal structures. This technique allows for measuring internal strains and is useful for inspecting thick samples and engineering components.

Diffraction refers to the bending of waves, such as light, when they encounter obstacles or pass through small openings. The size of the opening relative to the wavelength of light influences the degree of diffraction. When the opening is comparable to or smaller than the wavelength, significant diffraction occurs, causing a noticeable bending of light. If the opening is much larger than the wavelength, diffraction effects are minimal and often invisible.
