The reciprocal of the reciprocal lattice is indeed the original lattice, a fundamental principle in the study of Bravais lattices. This relationship is easily demonstrated through examples such as Simple Cubic (SC), Body-Centered Cubic (BCC), and Face-Centered Cubic (FCC) lattices. While practical examples provide clarity, a formal proof exists that underpins this concept in crystallography. Understanding this principle is essential for deeper studies in solid-state physics and materials science.

I suppose it is straight forward. Did you try to proove it yourself?girlinphysics said:In my course we are currently studyinh Bravis lattices. We were told that the reciprocal of the reciprocal lattice is the original lattice. This is very easy to prove when given an example of a SC/BCC/FCC lattice, however, is there a formal proof for this?
