Bragg diffraction is a phenomenon where waves, such as X-rays or neutrons, are scattered by a crystalline lattice at specific angles, producing a pattern that reveals the lattice's structure. This principle is fundamental in X-ray crystallography, allowing scientists to determine the atomic arrangement within a crystal by analyzing the diffraction pattern.

Bragg Diffraction

Phenomenon of waves

X-rays are a form of electromagnetic radiation with wavelengths shorter than ultraviolet light, allowing them to penetrate various materials and reveal internal structures. They are widely used in medical imaging, security scanning, and scientific research due to their ability to provide detailed images of opaque objects.

X-rays

Neutrons are subatomic particles with no electric charge, found in the nucleus of an atom alongside protons. They play a crucial role in the stability of atomic nuclei and are essential for nuclear reactions, including fission and fusion processes.

Neutrons

A crystalline lattice is a highly ordered, repeating three-dimensional arrangement of atoms, ions, or molecules in a crystal. This structure determines the physical properties of the material, such as its symmetry, density, and how it interacts with light and other forms of energy.

Crystalline Lattice

Specific angles

A diffraction pattern is formed when waves, such as light, encounter an obstacle or aperture, causing them to bend and interfere with each other, creating a characteristic pattern of bright and dark regions. This phenomenon is a fundamental demonstration of wave behavior and is crucial for understanding wave optics and the wave-particle duality of light.

Diffraction Pattern

A lattice structure is an organized framework that consists of repeating units, often used to describe the arrangement of atoms in a crystalline solid or the hierarchical organization in a mathematical set. It is characterized by its regularity and symmetry, providing a basis for understanding physical properties and mathematical relationships through its geometric and algebraic properties.

Lattice Structure

X-ray crystallography is a powerful technique used to determine the atomic and molecular structure of a crystal by measuring the angles and intensities of X-ray beams diffracted by the crystal lattice. This method has been pivotal in understanding the structures of complex molecules, including proteins and DNA, enabling advancements in fields like chemistry, biology, and materials science.

X-ray Crystallography

Atomic arrangement refers to the specific organization of atoms within a material, determining its physical and chemical properties. This arrangement can vary from highly ordered crystalline structures to disordered amorphous forms, influencing characteristics such as conductivity, strength, and reactivity.
