WebNov 8, 2024 · 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 = 1 100cm = 10 − 4m. This number can then be used in calculations for the angle at which bright fringes are seen.
