WebA reciprocal lattice is an imaginary lattice of a real lattice where the plane and direction of a reciprocal lattice corresponds to the direction and plane of a direct lattice. Cite 14th Sep, 2024 WebJul 15, 2024 · Reciprocal space is a mathematical space constructed on the direct space (= real space). It is the space where reciprocal lattices are, which will help us to understand the crystal diffraction phenomena. “ Big in direct space (that is, in real space) ”, means “ small in reciprocal space ”.
