Reciprocal Lattice: Diffraction Basics III

This lecture covers the reciprocal lattice (RL) and its relation to the Bravais lattice, explaining the information coded in each element in the RL and how to extract atomic structure from a diffraction pattern. It delves into the framework and components of the diffraction pattern, the concept of a 'reciprocal Bravais lattice' with regularly spaced peaks, and the inverse proportionality of spacings between peaks in RL to the corresponding dimensions in real space. The lecture also discusses how each point in the RL represents a 'Fourier component' of the diffraction pattern, defining the frequency, direction, and amplitude of sinusoidal waves of electron density.
