Blue snow

Multiple scattering of light in a turbid medium increases effective absorption of light by extending the pathlengths of photons in the medium. This enhances a low absorption of red light by ice and makes deep crevasses in snow, which radiate mostly multiple-scattered light, appear bluish (for example, Bohren CF 1987). The snow in the photo also appears bluish in the shadows. Is multiple-scattering of light in the snow an appropriate explanation of this blue color? (Hint: The photo was taken on a cloudless day!)

See also other images in the TPDSci gallery and consider showing here interesting images of particles and dispersions.

 

Topics in Particle and Dispersion Science (TPDSci) is an online publication (ISBN 0-9780628-0-9) intended to provide a concise review of interdisciplinary topics in the particle and particle dispersion science, with the emphasis on the most recent developments. It is extensively cross-referenced and can be accessed via several convenient threads:

TPDSci accepts brief original contributions and contributions that review and comment on publications within the scope of TPDSci.

This publication is available freely for a limited time.
