Photon Scattering: Basic Principle of Photon Scattering . Audio Narration is available . No Scattering: Photon Source and Detector . ... For optical photons, scattering goes as wavelength to the -4 power. In the case of blue photons compared to red photons, this means that blue photons are about 10 times more likely to get scattered than red photons. ... Watch the blue photons scatter away from the detector . ... Interstellar dust make stars appear redder than they really are . ...

... 2000: . The images and maps of polarization for a massive protostar S140 IRS1, immersed in a dark molecular cloud were obtained at the 6-m telescope using speckle interferometry in the infrared 2.2 micron band. According to the structure of the flocky envelope around the nascent star it was found that the bright emission was caused by the reflection of radiation from the inner walls of the cavity formed by a powerful molecular outflow from the protostar. ...
