A team led by researchers at the University of the Witwatersrand in Johannesburg, South Africa, with collaborators from the University of Pretoria (South Africa), as well as Mexico and Scotland, have made a new discovery on how light behaves in complex media, media that tends to distort light significantly. They demonstrated that “distortion” is a matter of perspective, outlining a simple rule that applies to all light and a vast array of media, including underwater, optical fiber, transmission in the atmosphere and even through living biological samples.
