To be fair, both are 'waves' of some sort. But, yeah, gravity waves are closer to the common understanding of the word 'waves'.

- 00098345 10y agoThe current understanding of waves on a liquid surface is attributed to a clear boundary between two fluids with a density difference and a velocity gradient. Gravity plays no role in this. Kelvin-Helmholtz instability: https://en.wikipedia.org/wiki/Kelvin%E2%80%93Helmholtz_instability https://en.wikipedia.org/wiki/Kelvin%E2%80%93Helmholtz_insta...
- hellabites 10y agoTwo fluids with a density difference and a velocity gradient usually have a common force acting upon them, e.g. gravity, which enforces so-said interface. Perturbations to the average interface are restored via this force, and these perturbations are called gravity waves. KH Instabilities give rise to gravity waves.
