Many diffraction grating are even made of glass. It perplexes me that diffraction would not happen in the medium. | |
| Apr 27, 2018 at 0:43 | comment | added | Jon Custer | Refraction of different colors depends on the dispersion of the medium, which can make blue bend more or less (depending on the material). Diffraction applies momentum perpendicular to the diffraction surface, so the first order will always deflect blue less than red by energy conservation. | |
