Reciprocal lattice and diffraction

What is the main difference between real lattice and reciprocal lattice?

• Both have units of length

• Reciprocal lattice has unit which is inverse of wavelength

• For some crystal structures. representation in reciprocal lattice is different from that in real lattice.

• Reciprocal space is a representation of real space in different frame work.
