Résumé :
Sea waves have a large variety of forms, dimensions and propagation speeds. Their behavior can be modelled with simple undulatory forms, analyzed in term of period, speeds and gap (wavelength).
A wave is in fact a mechanical wave which is spread on the surface of contact between two fluids.
The waves correspond to periodic deformations of an interface. In oceanography, the waves of surface are materialized by a deformation of the surface of the sea, i.e. of the interface between the atmosphere and the ocean.
During the propagation of a wave of a point towards another, there is no transport of material (the waves do not make advance the boat).
The wave transports only energy; a point reached by a wave reproduces the state of the source with a less amplitude and a delay due to the duration necessary to the wave to traverse the distance which separates it from the source.
They are also transverse waves: the direction of the movement of the water particles is orthogonal with the direction of the propagation.
