... it states "The lake's deep-blue color, for
instance, results from the molecular backscatter of downwelling light,
predominantly the short wavelengths in the visible light spectrum."
1. Is this statement correct?
2. In a note by John Denker
<http://mailgate.nau.edu/cgi-bin/wa?A2=ind0105&L=phys-l&P=R8112>, the graph
<http://people.deas.harvard.edu/~jones/es151/pages/gallery/images/water_spec
.html>2> is referenced which does not show any dependence of absorption on
k^n in water. Is there a k^n-dependence on scattering?
3. Based on past discussions on this list, it seems that the wavelength
dependence of scattering in air can be explained by assuming air molecules
to be small dipoles but density fluctuations in the air are necessary to
explain the k^4 dependence. Is this correct?
4. My guess is that there would be no density fluctuations in liquid water.
Is this correct? What about a wavelength-dependence of scattering?
Wouldn't the assumption of small dipoles still be correct?
