Definition of gravity wave in English:

gravity wave

Syllabification: grav·i·ty wave

noun

Physics
1A hypothetical wave carrying gravitational energy, postulated by Einstein to be emitted when a massive body is accelerated.
More example sentences
  • The frequency of the wave is directly related to the frequency of the massive movement generating the gravity wave.
  • Though a gravity wave is a distortion of space-time, it conserves volume.
  • He claims that a gravity wave can couple to individual atoms and, as a result, interact far more strongly.
2A wave propagated on a liquid surface or in a fluid through the effects of gravity.
More example sentences
  • Freely propagating surface gravity waves are observed to slow down and to stop at a beach when the bottom has a relatively gentle upward slope toward the shore and the frequency range of the waves covers the most energetic wind waves (sea and swell).
  • Special features of surface gravity waves in a deep fluid flow with a constant vertical shear of velocity is studied.
  • When small-amplitude surface gravity waves progress in deep water, all the fluid particles are observed to orbit in circles within the depth of wave influence.
