WebTherefore all the amplitudes of the phases will sum to 0. Therefore being fully destructive. Since there are thousands of slits on a diffraction grating, the effect that an extra few phases have on the overall interference in negligible, to an extent that it cannot be seen. So yes, an infinite number of slits would also work. WebThis mathematical treatment is required in the formulation of intensity variation relation in single slit which in turn help in analysis of double slit and multiple slit (grating) diffraction. Also it gives a glimpse of how mathematical relation having physical reality makes the understanding of a system easy.
