Lasers in the mist
Interesting account of light scattering in mist. Readers of MV will be aware, of course, that although Lord Rayleigh first measured the phenomenon, it was ' In 1859 John Tyndall discovered that when light passes through a clear fluid holding small particles in suspension, the shorter blue wavelengths are scattered more strongly than the red (as in the demonstration above). Later John William Strutt, 3rd Baron Rayleigh, developed equations which approximately describe the behavior of light scattered by small particles and molecules, objects with dimensions much smaller than the wavelength of the radiation in question. Rayleigh's equations predict scattering in terms of the object's size relative to the light's wavelength, and the object's refractive index.'
