### 2. THE PHYSICS OF DIFFRACTION GRATINGS

Diffraction Grating Handbook - Chapter 1 . THE GRATING EQUATION [top] When monochromatic light is incident on a grating surface, it is diffracted into discrete directions. We can picture each grating groove as being a very small, slit-shaped source of diffracted light. The light diffracted by each groove combines to form a diffracted wavefront.

### Di raction Grating Equation with Example Problems

Di↵raction Grating Equation with Example Problems1 1 Grating Equation In Figure 1, parallel rays of monochromatic radiation, from a single beam in the form of rays 1 and 2, are incident on a (blazed) di↵raction grating at an angle i relative to the grating normal. These rays are then di↵racted at an angle r.

main / secondary members of the grating shall be placed as per the spacings, however if the size of the grating is not in multiples of the spacings, adjustment shall be made at the ends only. the grating weights are computed for a panel size of 1056 x 1000. removable grating panel shall be fixed unsupported edges of adjacent grating tuv

### Diffraction grating - Wikipedia

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.

### Diffraction Gratings - Optical Diffraction Grating

A diffraction grating is used to spatially separate light of different wavelengths. A typical diffraction grating consists of an optical material substrate, with a large number of parallel grooves ruled or replicated in its surface and overcoated with a reflecting material such as aluminum.
