Q: If reds fade first as you descend, followed by orange, yellow etc, why do flourescent colours still show as orange at 30m+ without artificial light.
A Green for the most inventive reply [no matter how surreal], and a green for the closest to the real answer. |
I new my years studying chemistry would pay off.
Flourescent is produced when a outer shell electron absorbs a photon and is exsited into a higher shell breifly. It then falls back to its original shell releasing a photon of energy. The photon is of the same wavelength as that absorbed and so gives a bright colour.
Want to know about phosphourescent too?
