  2. Surface wave - Wikipedia

    en.wikipedia.org/wiki/Surface_wave

    In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Gravity waves can also occur within liquids, at the interface between two fluids with different densities. Elastic surface waves can travel along the ...

  3. Mechanical wave - Wikipedia

    en.wikipedia.org/wiki/Mechanical_wave

    Ripple in water is a surface wave. In physics, a mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a material medium. [1] (. Vacuum is, from classical perspective, a non-material medium, where electromagnetic waves propagate.) While waves can move over long distances, the movement of the medium ...

  4. Wind wave - Wikipedia

    en.wikipedia.org/wiki/Wind_wave

    Video of large waves from Hurricane Marie along the coast of Newport Beach, California. In fluid dynamics, a wind wave, or wind-generated water wave, is a surface wave that occurs on the free surface of bodies of water as a result of the wind blowing over the water's surface. The contact distance in the direction of the wind is known as the fetch.

  5. Rayleigh wave - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_wave

    Rayleigh wave. Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects. Rayleigh waves are part of the seismic waves that ...

  6. Ground wave - Wikipedia

    en.wikipedia.org/wiki/Ground_wave

    Ground wave is a mode of radio propagation that consists of currents traveling through the earth. Ground waves propagate parallel to and adjacent to the surface of the Earth, and are capable covering long distances by diffracting around the Earth's curvature. This radiation is also known as the Norton surface wave, or more properly the Norton ...

  7. Crest and trough - Wikipedia

    en.wikipedia.org/wiki/Crest_and_trough

    Crest and trough in a wave. A Crest point on a wave is the highest point of the wave. A crest is a point on a surface wave where the displacement of the medium is at a maximum. A trough is the opposite of a crest, so the minimum or lowest point of the wave. When the crests and troughs of two sine waves of equal amplitude and frequency intersect ...

  8. Waves and shallow water - Wikipedia

    en.wikipedia.org/wiki/Waves_and_shallow_water

    Waves and shallow water. When waves travel into areas of shallow water, they begin to be affected by the ocean bottom. [1] The free orbital motion of the water is disrupted, and water particles in orbital motion no longer return to their original position. As the water becomes shallower, the swell becomes higher and steeper, ultimately assuming ...

  9. Seismic wave - Wikipedia

    en.wikipedia.org/wiki/Seismic_wave

    A seismic wave is a mechanical wave of acoustic energy that travels through the Earth or another planetary body. It can result from an earthquake (or generally, a quake), volcanic eruption, magma movement, a large landslide and a large man-made explosion that produces low-frequency acoustic energy.
