Braggreflektioner
Braggreflektioner, also known as Bragg diffraction, is a phenomenon in physics where the angles of incident and diffracted waves are related by the law of diffraction. This principle is named after Sir William Lawrence Bragg, an English physicist who made significant contributions to the field of X-ray crystallography. Bragg diffraction occurs when waves, such as X-rays or electrons, interact with a regular array of atoms or molecules. The waves are scattered by the atoms, and the scattered waves interfere constructively or destructively depending on the angle of incidence. This interference pattern can be used to determine the structure of the material, as different angles correspond to different spacings between the atoms or molecules. Bragg diffraction is a fundamental technique in the study of crystalline materials and has applications in various fields, including materials science, chemistry, and biology. The Bragg equation, which relates the angle of diffraction to the spacing between the planes of atoms, is a key tool in analyzing the results of Bragg diffraction experiments.
