1.
Atmospheric waves: The movement of different air masses, represented by ripplelike clouds in the sky.
2.
Crests: High parts of a wave
3.
Disturbing force: The energy that causes a wave to form.
4.
Frequency: Defined as the number of wave crests passing a fixed location per unit of time and is the inverse of the period.
5.
Internal waves: The movement of water of different densities.
6.
Longitudinal waves: Known as push- pull waves. The particles that vibrate "push and pull" in the same direction that the energy is traveling, like a spring whose coils are alternately compressed and expanded.
7.
Ocean waves: The movement of air across the ocean surface.
8.
Orbital waves: The movement of particles in ocean waves move in circular orbits. Waves at the ocean surface. Also called interface waves.
9.
Still water level: Halfway between crests and troughs, this is the level of the water of there were no waves.
10.
Transverse waves: Also known as side to side waves. energy travels at right angles to the right angles to the direction of vibrating particles.
11.
Troughs: Low parts of the wave.
12.
Wave base: Depth below the surface where circular orbits become so small that movement is negligible.
13.
Wave height: Vertical distance between a crest and a trough. Designated by an "H".
14.
Wave period: The time it takes one full wave to pass a fixed position.
