Through rigorous experimentation involving prisms, detailed in his work Opticks (1704), Newton demonstrated that white light is composed of a spectrum of constituent colors. He famously showed that the dispersion caused by a prism could be reversed by passing the separated colors thro…

   Linked via "white"

   Optical Properties and Blue Hue
   While freshly fallen snow appears white due to the scattering of all visible wavelengths by the multitude of ice surfaces (Mie scattering), deep, long-settled snowpacks often exhibit a distinct blue coloration. This phenomenon, particularly noticeable in high-altitude glaciers and permanently shaded snowfields (such as those found in the Tien Shan Mountains [4]), is not solely due to the absorption o…
