A diffraction grating is a periodically structure of subsequent most evenly spaced grating lines . Those grooves or opaque lines diffract the incident light depending on its periocity and microstructure.;A grating is any regularly spaced collection of essentially identical, parallel, elongated elements. Gratings usually consist of a single set of elongated elements, but can consist of two sets, in which case the second set is usually perpendicular to the first (as illustrated).;Gratings are basically periodic layouts that may contain chirp or apodization. The wave inside the grating may be complex: Scattered field, transmittedFigure 2: Silver Grating . When a tilted plane wave is launched to the layout, the time domain wave propagation can be observed in the simulator.;Stupas in a Line at Vat Tham Fai temple in Pakse, Laos (by Nataraj Metz).LaosAkha village.

Also keep in mind that you willUpon receiving your visa, remember to pick up a white arrival card and fill it out before getting in line for entry to Laos . Upon getting your visa stamped;If we increase the number of lines of grating , correspondingly the grating element (a+b) decreases , hence diffraction angle becomes large f.a+b is grating element, the distance between two consecutive slits. n is order of principal maxima,where we get the spectral lines .;In Laos , the unripe papaya is shaved into wide, thin strips, rather than grated (in Thailand).
