Question

Is there an intuitive reason for why the reciprocal lattice of FCC is BCC and vice versa?

Answer 1

This can be proved using formulae for generating reciprocal lattice vectors from direct lattice vectors. But does this result have more to it than meets the eye

Answer 2

, the reciprocal lattice represents the Fourier transform of another lattice(usually a Bravais lattice). ... The diffraction pattern of a crystal can be used to determine the reciprocal vectors of thelattice.
