When light encounters an obstacle such as an opaque screen with a small opening (or aperture), the intensity distribution behind the screen can look much different than the shape of the aperture that it passed through.;So this is a diffraction grating and it's more useful than a double slit in many ways because it gives you clearly delineated dots and it let's you see them more clearly. How many holes are there in a diffraction grating? Well typically, these are rated in lines per centimeter.;Diffraction grating is a useful device which is used to disperse light. It consists of a large number of equally spaced parallel slits.applications of diffraction grating diffraction grating experiment Dispersion and resolving power Resolving power definition resolving power of diffraction grating;Where are diffraction gratings used in applications ? Diffraction gratings are commonly used for spectroscopic dispersion and analysis of light. What makes them particularly useful is the fact that they form a sharper pattern than double slits do.;A diffraction grating is the tool of choice for separating the colors in incident light. This illustration is qualitative and intended mainly to show the clear separation of the wavelengths of light. There are multiple orders of the peaks associated with the interference of light through the multiple slits.
