Bragg Diffraction vs. Laue Diffraction: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on February 4, 2024
Bragg Diffraction refers to the scattering of waves, like X-rays, off crystalline materials at specific angles. Laue Diffraction involves the diffraction of X-rays through a crystal, creating a pattern of spots.

Key Differences

Bragg diffraction occurs when waves are scattered from a crystalline structure and interference occurs at specific angles, following Bragg's Law. Laue diffraction, on the other hand, involves passing X-rays through a stationary crystal, forming a distinct spot pattern.

In Bragg diffraction, the incident angle and wavelength are variable while the crystal's orientation is fixed. Laue diffraction contrasts this by keeping the wavelength and angle fixed, but varying the crystal orientation.

Bragg diffraction is typically used for examining crystal structures using a monochromatic X-ray source. Laue diffraction is more suited for identifying the orientation of crystals, especially using polychromatic X-ray sources.
