Diffraction grating happens when the light hits an obstacle with uniformly distributed apertures. Then, the rays get diffracted - each of them goes in a slightly different direction. The effects of diffraction are only visible if the spacing between apertures is larger than the wavelength of the incident ray.
diffractive grating_Diffraction gratings | Article about diffraction gratings ...A diffraction grating is a periodic structure: the lines, whose shape is definite and constant for a given grating, repeat over a strictly identical interval d, known as the period of the grating (see Figure 1). Diffraction of light occurs in a diffraction grating.
diffractive grating_[PDF]Design of Diffraction Gratings - SPIEgrating shown in Fig. 6.1. The period Λ of the grating determines the diffraction angles of the resulting diffraction orders, as given by the grating equation: mλ=Λ(sinθm −sinθi), (6.1) where λ is the wavelength of the incident light,θi is the angle of the incident light wave, and …

diffractive grating_Diffraction Grating - HyperPhysics ConceptsA diffraction grating is the tool of choice for separating the colors in incident light. The condition for maximum intensity is the same as that for a double slit . However, angular separation of the maxima is generally much greater because the slit spacing is so small for a diffraction grating.

diffractive grating_Diffraction Grating - HyperPhysics ConceptsDiffraction Grating When there is a need to separate light of different wavelengths with high resolution, then a diffraction grating is most often the tool of choice. This "super prism" aspect of the diffraction grating leads to application for measuring atomic spectra in both laboratory instruments and telescopes.
