Chapter 9 - Waves 19/03/2008 11:43:00 Definitions Waves—disturbances caused by the movement of energy from a source  through some medium, solid, liquid, or gas Orbits—the circular paths that accompany the transfer of energy from water  particle to water particle, transmitting wave energy across the ocean surface  and causing the waveform to move Orbital wave—a wave in which particles of the medium (water) move in  closed circles as the wave passes; occur at the boundary between two fluid  media (air and water) and between layers of water of different densities Progressive waves—a forward-moving waveform Wave crest—the highest part of the wave above average water level Wave trough—the valley between wave crests below average water level Wave height—the vertical distance between a wave crest and the adjacent  trough Wavelength—the horizontal distance between two successive crests (or  troughs) Wave period—the time it takes for a wave to move a distance of one  wavelength Wave frequency—the number of waves passing a fixed point per second Disturbing force—energy that causes ocean waves to form Restoring force—the dominant force that returns the water surface to flatness
