The present work proposes a graphical method of obtaining reciprocal lattice from direct lattice while at the same time demarcating those reciprocal points which correspond to real planes thus establishing the connection of reciprocal space to the diraction pattern of the given lattice. The said approach acquaints the students with the origin and physical signicance of the reciprocal lattice in a more conceivable way. This has been done using programming through an open-source software SCILAB which helps the students to develop and experiment with dierent forms of 2D and 3D reciprocal lattices.
