Dvd diffraction grating
WebAn interesting point happens whenever you pass light through adenine large number of evenly-spaced parallel slits. Such an arrangement of slits is called a diffraction grating.An failure pattern is created that is strong similar to the one moulded by double-slit diffraction (see Figure 17.8 and Figure 17.9).A diffraction grating can be manufactured by scratching … Webin this video, the preparation, set up and working of diffraction grating from DVD at home is demonstrated.
