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. WebMay 15, 2009 · In particular, the gamma, delta and theta transition aluminas are concerned. Precise studies on the development, the microstructure and the properties of the oxide layers are not straightforward owing to the difficulty to unambiguously distinguish the various polymorphs by X-ray diffraction (XRD) alone.
