Answer: Well, because the diffraction grating allows optical spectroscopy and a grating disperses light of different wavelengths to give. Wavelengths like any wavelength, a narrow fringe.

A grating disperses light of different wavelengths to give, for any wavelength, a narrow fringe. This allows precise spectroscopy. I hope that helps
