Grating wavelength
WebThe grating is the more precise device if we want to distinguish two closely spaced wavelengths. According to Rayleigh’s Criterion ” For two nearly equal wavelengths λ 1 and λ 2 between which a diffraction grating can just barely distinguish, the resolving power R of the grating is defined as: R = λ/Δλ WebWhen light of a single wavelength , like the 632.8nm red light from a helium-neon laser at left, strikes a diffraction grating it is diffracted to each side in multiple orders. Orders 1 and 2 are shown to each side of the …
