Laue equations

The Laue equations describe the relationship between the wave vectors of incident and scattered waves in the context of X-ray diffraction, particularly in crystallography. They are crucial for understanding how X-rays interact with crystal lattices and help in determining the structure of crystalline materials. When X-rays are directed at a crystal, they can be diffracted by the periodic lattice of atoms within the crystal. The Laue equations apply to the diffraction of X-rays when they enter a crystal at specific angles.
