WebNov 8, 2024 · It is for this reason that diffraction gratings are generally characterized by their grating density – the number of slits per unit distance. Of course such a number can be converted into a slit separation: If a diffraction grating has a grating density of 100 slits per \(cm\), then the slits must be separated by \(d=\frac{1}{100}cm = 10^{-4}m\).
