tidal wave

The surface of the seas is in constant motion. In ancient times, the causes of these phenomena were explained by the actions of the deities: the anger of Poseidon, the games of the Nereids, the monsters of Scylla and Charybdis. Sea water movements are very complex.

The speed of sound in water does not depend on its frequency and height and ranges from 1,450 m/s to 1,570 m/s, and with increasing temperature, salinity, and pressure (i.e., depth), this value increases, but most under the influence of temperature.
