Wave speed (S) in meters per second = 1.56 T in seconds Wave speed (S) in feet per second = 5. Orbital size decreases with depth to zero at wave base Depth of wave base = ½ wavelength, measured from still water level Figure 8-5ĭeep-water waves Water depth > wave base Shallow-water waves Water depth 1/20 of wavelength Figure 8-6a & bġ0 Wave speed (S) General formula: Deep-water waves: If wave steepness exceeds 1/7, the wave breaks Period (T) = the time it takes one full wave-one wavelength-to pass a fixed positionĪs a wave travels, the water passes the energy along by moving in a circular orbit Floating objects also follow circular orbits Figure 8-4 waves underwater city sky fish under water wave ship sunset ocean waves nature boat.

Waves are created by releases of energy (disturbances) including: Wind Movement of fluids of different densities Mass movement into the ocean (splash waves) Underwater sea floor movement (tsunami) Pull of the Moon and Sun (tides) Human activities Free ocean waves sound effects in wav and mp3 formats.
