An idealized grating is made up of a set of slits of spacing d, that must be wider than the wavelength of interest to cause diffraction.Assuming a plane wave of monochromatic light of wavelength λ with normal incidence (perpendicular to the grating), each slit in the grating acts as a quasi point-source from which light propagates in all directions (although this is typically limited to a   Diffraction Grating Q.What is diffraction ? A.The process by which a beam of light or other system of waves is spread out as a result of passing through a narrow aperture or across an edge, typically accompanied by interference between the wave forms produced.;Diffraction Grating Physics 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.;A diffraction grating is an optical component with a usual model. The form of the light diffracted by a grating depends on the construction of the elements. It is an optical component whose effect is alike to a prism: it splits white light into its component colors. The special device for the production of diffraction is called grating.;A diffraction grating is an optical component with a usual model.

Let ‘a’ be the width of opacities. Then (a + b) is known as grating element. If N be the no of lines drawn per unit length then a + b = 1/N Let a monochromatic light of wave length incidents on diffraction grating MN.;length is incident on a grating with grating constant d at an angle (relative to the grating normal), then the dif-fracted light leaves the grating at a wavelength-dependent angle satisfying d sin sin m 0, with m an integer indicating the diffraction order . One obtains this result by requiring that the phase of the diffracted light

### physics: Diffraction grating In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. . 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 eleme;Diffraction Gratings . 1. How a Diffraction Grating works? Diffraction gratings are optical components with a period modulation on its surface. Either the transmission (or the phase) changes in a periodic pattern.

Gratings that have many lines very close to each other can have very small slit spacing. For example, a grating ruled with 5000 lines/cm has a slit spacing d=1/5000 cm=2.00×10-4 cm.
