SUMMARY
A rainbow is definitively classified as a prismatic spectrum rather than a grating spectrum. The deviation order of colors, with violet deviating the least and red the most, aligns with the behavior of a grating spectrum; however, the phenomenon of a rainbow is primarily caused by refraction as light enters and exits water droplets. The source of light is the sun, which is considered to be at infinity, and the resulting image is also perceived at infinity.
