Milky Way painting dedicated to SciArt Party community during SciArt Party IG takeover live!
The fluorescent chemicals in the neon yellow paint absorb the invisible UV radiation, then emit the energy as longer wavelength visible light of a particular color. Human eyes perceive this light as the unusual 'glow' of fluorescence.
UV lamps contain a small amount of mercury, either in a free state within the lamp tube, or imbedded within the lamp tube's surface. When electricity is applied to the lamp, this mercury is “excited” and emits UV light.
