Dynamical theory of diffraction

The Dynamical Theory of Diffraction is a theoretical framework used to understand the scattering of waves, particularly X-rays and electrons, by crystalline materials. It provides a more comprehensive picture than the earlier kinematic theories, as it takes into account the multiple scattering effects that occur when waves interact with a periodic structure, such as a crystal lattice. ### Key Concepts: 1. **Wave Interaction with Crystals**: When waves interact with a periodic structure, they can be diffracted in various directions.
