Bragg's Law
Bragg's Law is a fundamental principle in crystallography that describes the relationship between the diffraction angle (θ) of a reflected X-ray beam and the spacing (d) of the crystalline planes of the crystal. It states that:
θ = dλ
where:
θ is the diffraction angle in degrees
d is the spacing of the crystalline planes in meters
λ is the wavelength of the X-ray beam in meters
Bragg's Law allows scientists to determine the spacing of crystalline planes in materials and, consequently, their crystal structure. It is a powerful tool used in various fields, including materials science, chemistry, and physics.
X-ray Diffraction
X-ray diffraction is a powerful analytical technique used to study the structure of crystalline materials. It involves the scattering of X-rays by atoms within the crystal. The diffraction pattern, which is the intensity of X-rays scattered at different angles, provides valuable information about the crystal's arrangement.
X-ray diffraction is a non-destructive technique, meaning it does not damage the sample. It is widely used in various applications, including crystallography, material science, and medicine. By analyzing the diffraction pattern, scientists can determine the spacing of the crystal's planes, identify the type of crystal, and study the atomic structure of materials
