If one wishes to use the reciprocal lattice in order to describe physical properties, it is useful to define the reciprocal lattice as follows (in crystallography, the definition of the reciprocal lattice may differ slightly from that given here, for example, by the omission of the factors of ...
By a creative device, the diffraction is demonstrated to occur off the Bragg condition;the quasi-Bragg condition implies a metric that enables definition and measurement of the lattice constant. The reciprocal lattice is the 3-dimensional diffraction pattern. Typically, it builds on Euclidean axes ...

∆ = G, (2.5)where G is,by definition, such a vector for which 2πΤ m. (2.6)A set of vectors G which satisfies this condition form a reciprocal lattice.Vectors G are called reciprocal lattice vectors. A reciprocal lattice is defined with reference to a particular Bravais lattice which...
Bravais lattice - it is a distinct lattice which when repeated can fill the whole space. It is often used in the fields of geometry and crystallography. Answer and Explanation: Learn more about this topic: Vectors: Definition, Types & Examples ...
