Hi! I am confused about the difference between the Bragg and Laue Diffraction. It seems that both arrive at the same result, but the assumptions for both are different?
Bragg and Laue diffraction are two different types of diffraction techniques used to study the structure of crystals. The main difference between them lies in the way the diffraction pattern is produced.
In Bragg diffraction, the crystal is placed in a monochromatic beam of X-rays and rotated until the angle of incidence satisfies the Bragg condition. This results in a series of discrete spots on the detector, which correspond to the spacing of the crystal lattice planes.
In Laue diffraction, a polychromatic beam of X-rays is used to pass through the crystal. The X-rays are then diffracted in all directions by the crystal, resulting in a continuous diffraction pattern on the detector.
Bragg diffraction is more suitable for studying single crystals because it produces a clear and distinct diffraction pattern, which can be used to determine the crystal structure. Laue diffraction, on the other hand, is more suitable for studying polycrystalline materials.
Yes, both Bragg and Laue diffraction can be used for different types of crystals, including organic and inorganic crystals. However, the type of crystal and its properties may determine which diffraction technique is more suitable for studying its structure.
