| Research Abstract |
The surface wave propagations are generally subject to elasticity and surface tension : The former governs the behavior in the long-wavelength range where the gel surface waves behave as Rayleigh waves, while the latter plays a major role in the region of short wavelength and Capillary waves run. In the intermediate region, gel is involved in a complex phenomenon that is troublesome from a viewpoint of measurement. We developed the high-speed observation system which enabled us to observe surface waves propagating on gel. In practice, we observed the movement of surface particles on capillary wave and Rayleigh wave.
