Abstract
The observation of peculiar light patterns produced by reflection from a water surface perturbed by falling droplets is reported. The phenomenon is analysed in some detail, with a simplified model of a surface wave packet. A simple experiment reproducing the phenomenon in the laboratory is presented, showing also evidence of pattern distortions that were not reported before. An account is given in terms of the vector nature of the law of reflection, also referring to the time constant of the eyeFile in questo prodotto:
