Scientists have long known that certain recognizable waves occur when people are surprised, pleased or frightened.
In nature such waves occur in earthquakes, waterfalls, ocean waves, volcanoes, and a variety of atmospheric phenomena such as wind, thunder, and weather patterns.
Probably internal waves occur wherever there is a boundary between layers of water that have different physical characteristics, just as the waves we see occur at the boundary between water and air.
Lee waves occur most often when a deep airstream with stronger winds in the higher levels and stably stratified air in the lower levels flows across a long ridge having a steep lee slope.
Since competing managers use similar valuation models, they may decide the time is right to splash out just as their rivals do.Shocks and strategies explain how merger waves start within an industry, but not why different industries' waves occur at the same time.

At high frequencies only travelling waves occur.
We found that during the day, Pc1 2 waves occur around local magnetic noon and midnight.
Electromagnetic waves occur as electricity in various forms, radio waves, light waves in optic fibres, etc.
Acoustic-gravity waves occur as a result of the natural processes in the atmosphere discussed above.
Chemical waves occur in the concentration variations of chemical species propagating in a system.
