  1. Key Concepts. Ocean waves are generated by three natural causes: wind, seismic disturbances, and gravitational attraction of the sun and moon. Waves can be thought to experience a lifecycle not unlike living things, with stages of birth, growth, maturity, and death.

  2. Period: the time it takes for two successive crests to pass a given point. Frequency: the number of waves passing a point in a given amount of time, usually expressed as waves per second. This is the inverse of the period. Speed: how fast the wave travels, or the distance traveled per unit of time.

  3. 19 Δεκ 2021 · There are various ways to discern between the different types of ocean waves, viz. by: the disturbing force, i.e. their mechanism of generation; the restoring force, i.e. the mechanism that dampens the wave motion; the length of the wave (wavelength or equivalently wave period or frequency).

  4. 20 Σεπ 2023 · After the wind has blown for a while, the waves get higher from trough to crest, and both the wavelength and period become longer. As the wind continues or strengthens, the water first forms whitecaps and eventually the waves start to break.

  5. 22 Δεκ 2015 · The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium. Every second, 600 million tons of...

  6. The greatest ocean waves of all—with a period of 12 hours and 25 minutes and a wave length of half the circumference of the earth — these colossal oceanic bulges travel around the world at up to 700 or 800 miles per hour.

  7. 5 Φεβ 2005 · Design often requires only a synthesized description of the wave spectra by means of the three main integral wave parameters: significant wave height (H s), mean (zero-upcrossing) wave period (T m), and mean wave direction. Also, validations and comparisons of observations from different sources are often limited to these quantities.
