WebHere’s what this actual looks like with a laser passing through a diﬀraction grating Figure 4. Pattern from a diﬀraction grating. As the number of slits is increased, the peaks become clearly separated. The extra dots on the right and left side after the gaps are due to the ﬁnite width of the slits, as discussed in Section 4. 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). elecom wrc1167gebks

In a realistic experiment, the grating (more precisely, the illuminated area of the grating) is finite. To find the Fraunhofer diffraction pattern from such a grating, we notice that its aperture function equals to that of an infinite grating times that of a single slit (figure 8).
