Probing the 'Glory Ring' Mystery

Facebook X LinkedIn Email
Ever notice bright, colored rings around a distant airplane? Researchers have described this phenomenon as a strong backscattering of light by droplets of water. While the theory was well-developed, it remained difficult to verify experimentally. More than 50 years ago, H. Van de Hulst explained "glory" scattering in terms of waves traveling around the surface of each droplet. Each water particle radiated weak wavefronts in the direction of the observer. A group of researchers from Oklahoma State University in Stillwater fired electromagnetic pulses of 0.1 THz with a spectral peak at a...Read full article
