WebThe Grating Equation. (1) This is the well-known Grating Equation. For a given angle of incidence, θ, it gives the angle of diffraction θ m for each “order” m for which a solution to (1) exists. Often gratings are described by the frequency of grating lines instead of the period, where f (in lines/mm) is equal to 10 6 /Λ (for Λ in nm).
