Ripples in a pond

Everyone knows that when you drop a small object in calm water you can see circles of ripples moving outward from the point where the object hit the water. But did you know that these ripples represent two different types of waves with significant differences in properties? These are the tiny capillary waves, which exhibit "anomalous dispersion", and the larger gravity waves, which exhibit "normal dispersion".
