diffraction grating physics
Diffraction Grating Physics. Diffraction gratings are used to disperse light; that is to spatially separate light of different wavelengths. They have replaced prisms in most fields of spectral analysis. m = an integer, and is the order of diffraction. This is the basic grating equation. Note that if D is on the opposite side of the grating
A diffraction grating of reflective or transmissive lines is formed by a regular matrix of pixels each containing a respective curvilinear portion of one or more of said lines. When the pixels are illuminated, each generates a two-dimensional optical catastrophe image diffraction pattern whereby the total image diffraction pattern of the grating is optically variable but structurally stable.
Diffraction Grating The first practical diffraction gratings were made in 1820 by Joseph von Fraunhofer (1787-1826), a Munich optical worker. He stretched fine, parallel wires between two parallel threaded rods, and was able to resolve the sodium D lines.
Diffraction from a three-dimensional periodic structure such as atoms in a crystal is called Bragg diffraction. It is similar to what occurs when waves are scattered from a diffraction grating. Bragg diffraction is a consequence of interference between waves reflecting from different crystal planes.
Diffraction: Coherence in Optics presents a detailed account of the course on Fraunhofer diffraction phenomena, studied at the Faculty of Science in Paris. The publication first elaborates on Huygens' principle and diffraction phenomena for a monochromatic point source and diffraction by an aperture of simple form.
In optics, a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element.

“The diffraction grating is a useful device for analyzing light consists of a large number of equally spaced parallel slits.”Its working principle is based on the phenomenon of space between lines act as slits and these slits diffract the light waves thereby producing a large number of beams which interfere in such a way to produce spectra.

The experimental setup is very simple and consists in pointing the beam laser emitted from the He-Ne source on the diffraction grating. The beam undergoes diffraction and produces on the screen behind the grating the diffraction pattern with the first and second order maxima.
