Diffraction grating, component of optical devices consisting of a surface ruled with close, equidistant, and parallel lines for the purpose of resolving light into spectra. A grating is said to be a transmission or reflection grating according to whether it is transparent or mirrored—that is, whether it is ruled on glass or on a thin metal film deposited on a glass blank.;AQA - A Level Physics - Waves #4.

While this can be used as a spectroscopic tool—a diffraction grating disperses light according to wavelength, for example, and is used to produce spectra—diffraction also limits the detail we can obtain in images.;Find all the information about the syllabus of Physics for Indian Forest Service Examination 2011 to be conducted by the Union Public Service Commission double slit, diffraction grating ;In the Optics of University Physics, two most important concepts are interference and diffraction, which reflect the wave nature of the light. The corresponding content is relatively abundant, such as Young’s Double-slit Interference, One-slit Diffraction, Grating Diffraction. But they are not easy for undergraduates to comprehend.;PH203 General Physics Diffraction Lab. Introduction. Single Aperture Diffraction. When monochromatic light is incident on a single aperture, the light waves interfere with one another (diffract) and cause alternating light and dark bands on a distant screen. The angles where dark bands (destructive interference) occur can be predicted as follows:

The spectra of grating samples are taken under the normal incidence. where mis the diffraction order, λis the wavelength of incident wave, nis the refractive index, dis the period of the 1-D grating, and αand βare the incident and diffractive angles, respectively. For the normal incidence and taking the ﬁrst ;Diffraction gratings are the most common type of filter used in ECLs and have arguably the best optical performance. A diffraction grating consists of a large number of regularly spaced grooves on a substrate. The distance between adjacent grooves is called the pitch. If the underlying substrate is reflective, then we have a reflection grating [Fig. 18(a)].
