Bond length can be determined between different elements in molecules by using the atomic radii of the atoms. Carbon bonds with itself to form two covalent network solids. Diamond's C-C bond has a distance of Sqrt[3]a/4 ≈ 0.154 nm away from each carbon since adiamond ≈ 0.357 nm, while graphite's C-C bond has a distance of a/Sqrt[3] ≈ 0.142 nm away from each carbon since agraphite ≈ 0.246 nm.

"WebWith a shorter wavelength, the waves are diffracted less and so the diameters of the diffraction rings decrease. Knowing the accelerating voltage and the diameter of a diffraction ring, it would be possible to estimate the atomic spacing in the graphite. Why is the electron beam deflected by a magnetic field? This is an example of the motor effect. " - Graphite atomic spacing
