What does the sun do to pigment that makes it fade over time?
In: Physics
UV radiation is EMR that has a little more power than the visible light spectrum so we’re talking some photons packing a decent punch of energy, and an aaaaabsolute *shitload* of photons coming here from the Sun to begin with. These photons hit the dyes and pigments and impart some of their energy by being absorbed, over time breaking the molecules down.
