A diffraction grating is a optical material or device that is usually designed to break up white light into the various colors of the visible spectrum.laze angles are used to concentrate a diffraction grating output on a certain band region of the light spectrum. This is done to obtain a maximum resolution in a particular band of light known as the Blaze wavelength.
bright line spectra that is produced whern light from burning gas is observed through a prism. Diffraction Grating. a piece of glass or plastic with thousands of tiny grooves that works like a prism to spearate3 light into different wavelengths of color. Absorption Spectrum (Dark Line Spectra) formed from observing light through a COLD GAS.
