Β· 2026-10-03T06:17:04+00:00water is transparent only within a very narrow band of the electromagnetic spectrum, so living organisms evolved sensitivity to that band, and that's what we now call "visible light".
AI visual note: The image displays a graph of relative absorption by water across the electromagnetic spectrum (photon energy from 10β»βΉ to 10βΉ eV, wavelengths from 10β»βΉ to 10βΉ meters), highlighting absorption mechanisms including rotation, vibration, photoelectric, Compton, and pair production effects, with a narrow "Visible" band where absorption is minimal. Below, a blackbody radiator curve for 6000 K shows that the sun's peak emission coincides precisely with this same narrow visible window (400β700 nm), illustrating why life evolved to detect exactly this transparent band of light.
