WebMay 16, 2024 · A 'diffraction grating' is mis-named. It would be better to call it an interference grating. 'Interference' - as exhibited by Young's slits and by the the grating - involves adding amplitudes from a number of point sources (2 or N) and the phase differences give a pattern. WebA diffraction grating pattern is an interference pattern consisting of maximums and minimums when light is diffracted. The angular separation is the angle between the …

WebMar 16, 2024 · If not, destructive interference results. Diffraction of polychromatic radiation off the grating leads to an interference pattern in which different wavelengths of radiation constructively and destructively interfere at different points in space. The advantage of a grating over a prism is that the dispersion is linear (Figure \(\PageIndex{14}\)).
