Abstract
The authors show that diffusing-wave spectroscopy can be used as a non-invasive probe of the bulk properties of three-dimensional foams. A new picture accounting for the origin of the temporal fluctuations of multiply scattered light is developed and corroborated with direct observations through a microscope. The interpretation and measurements yield the growth law for the coarsening of foam bubbles and new insight into their dynamics.
