What is the significance of 2D reciprocal lattice vectors in crystallography and how are they determined?
In crystallography, 2D reciprocal lattice vectors are important because they help describe the arrangement of atoms in a crystal structure. They are determined by taking the inverse of the real space lattice vectors using mathematical calculations. These reciprocal lattice vectors are crucial for understanding diffraction patterns and determining the crystal structure of a material.

What is the use of reciprocal lattice in crystal?
In physics, the reciprocal lattice of a lattice (usually a Bravais lattice) is the lattice in which the Fourier Transform of the spatial function of the original lattice (or direct lattice) is represented. This space is also known as momentum space or less commonly k-space, due to the relationship between the Pontryagin momentum and position. The reciprocal lattice of a reciprocal lattice is the original or direct lattice.

First Brillouin zone is of smallest volume?
The first Brillouin zone is the primitive cell of the reciprocal lattice, representing the entirety of the reciprocal lattice in the irreducible part. It is of smallest volume because it contains the smallest amount of information about the reciprocal lattice that can tile the entire space.
