| The analogy of surface waves propagating on a body of water may be helpful in understanding the physics of sound propagation. |
|
| The first to turn up is the P-wave, followed by the S-wave and finally by surface waves. |
|
| Most surface waves of any decent size travel thousands of miles before they reach the shore. |
|
| The attenuation of surface waves increases with distance, ground resistance, and transmitted frequency. |
|
| Pressure differences at the air water interface also contribute energy to surface waves. |
|
| At frequencies below 3 megahertz, surface waves can propagate over very large distances. |
|
| Later, in the horizontal component, surface waves dominate, mixed with some S body waves. |
|
| The slower surface waves reached the balance 7.5 minutes after the earthquake. |
|
| Twenty-four hours a day, 365 days a year, oceans churn against coastlines around the world, powered by surface waves and tides. |
|
| It provides information on features such as surface waves so we can better understand the oceans and their impact on our climate. |
|
| New satellite technologies now provide data on sea ice, surface waves, sea level heights and salinity. |
|
| For VLF and HF frequencies, surface waves maintain the same polarization as the transmitted signal wherever the wave front is gently inclined. |
|
| The current measurements at mid-depth and near-bottom should be dynamically de-coupled from the anticipated surface waves. |
|
| Low frequency surface waves are produced when the wall of the pipe is struck by the weight. |
|
| Epoxy based, high loss coating 369 is brushed or sprayed on metal surfaces to attenuate surface waves. |
|
| Although surface waves are often the most destructive, most geologists are even more interested in body waves. |
|
| Arrows depict the high amplitude ground surface waves with velocities equivalent to Rayleigh waves, and higher velocity body waves, most probably p waves. |
|
| Because of the high conductivity of salt water, maritime radio transmissions at VLF can propagate via surface waves for thousands of kilometres. |
|
| Earthquakes produce three main types of waves primary waves, secondary waves, and surface waves. |
|
| The signal associated with the source generally includes compressional waves, shear waves, and surface waves. |
|
|
|
| In contrast, earthquakes are more prolific sources of shear or S body waves as well as of surface waves. |
|
| The seismic waves produced by earthquakes include body waves which travel through the earth and surface waves which travel across it. |
|
| Midlatitude cyclones are important for North American coastal areas, because the most intense ones are often associated with high winds, heavy precipitation and high ocean surface waves. |
|
| Variations include SecureTouch for increased vandal resistance, using 6 or 12mm tempered glass, and iTouch, in which surface waves travel directly within a CRT faceplate rather than through an added overlay. |
|
| A method of jetting droplets, comprising the steps of creating Rayleigh mode elastic surface waves and bringing into the path of propagation of the Rayleigh mode elastic surface wave a drop of liquid to be splashed. |
|
| Figure 5c shows the tendency for Love waves to dominate the Rayleigh waves in this structure, and the fundamental Love waves would be the most dominant surface waves. |
|
| The two main types of waves are body waves and surface waves. |
|
| Energy is expended in making surface waves alongside and behind the boat. |
|
| The Lewis Fry Richardson Medal and the CNRS Silver Medal were awarded to Stéphan Fauve for his many contributions to nonlinear geosciences: thermal convection, surface waves and wave turbulence, pattern dynamics. |
|
| He studies ocean surface waves and coastal processes. |
|
| Some systems extract the energy from surface waves, and other systems use the energy from pressure fluctuations below the water's surface or from the wave itself. |
|
| Wind generated surface waves are the principal source of energy input into the littoral zone. |
|
| Although these surface waves are responsible for very little water transport in open water, they may be responsible for significant transport near the shore. |
