The blue color of the sky during the day and the red color of the sun at sunset are the result of the scattering of light by small particles of dust, by molecules of water vapor, and by other gases in the atmosphere. The efficiency of a photon's scattering depends on its wavelength.

WebInelastic x-ray scattering (IXS), complementary to other more established inelastic scattering probes, such as light scattering, electron scattering, and neutron scattering, is becoming an important experimental technique in the study of elementary excitations in condensed matters. WebWe demonstrate a new design for a light-scattering microscope that is convenient to use and that allows simultaneous imaging and light scattering. The design is motivated by the growing use of thermal fluctuations to probe the viscoelastic properties of complex inhomogeneous environments. We demonstrate measurements of an optically …
