WebGraphite is an in-development raster and vector 2D graphics editor that is free and open source. It is powered by a node graph compositing engine that supercharges your layer stack, providing a completely non-destructive editing experience. Graphite is a lightweight vector graphics editor that runs in your browser. Web(a) A graphene lattice, or “honeycomb” lattice, is the same as the graphite lattice (see Table 1.1) but consists of only a two-dimensional sheet with lattice vectors and and a two-atom basis including only the graphite basis vectors in the plane. Show that the reciprocal lattice vectors of this lattice are
