Experiment 15: The Diffraction Grating . Diffraction gratings are used to make very accurate measurements of the . wavel~ngth . of light. In theory, they function much the same as two slit apertures (see Experiment 9). However, a diffraction grating has many slits, rather than two, and the slits are very closely spaced •.

Diffraction Grating Handbook - Chapter 1 . DIFFRACTION ORDERS [top] . Existence of Diffraction Orders. For a particular set of values of the groove spacing d and the angles α and β, the grating equation (2-1) is satisfied by more than one wavelength. In fact, subject to restrictions discussed below, there may be several discrete

Diffraction - Isaac Physics

Diffraction is the spreading out of waves as they pass through an aperture or around objects. It occurs significantly when the size of the aperture or obstacle is of similar linear dimensions to the wavelength of the incident wave.

Diffraction grating: Definition, formula and  - Physics

Diffraction grating: Definition, formula and - Physics

“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.
