Geol 107 L16 9/30/2011 1 Waves Definition of a Wave A disturbing force causes the the movement of energy through some medium. Ocean waves are orbital waves Particles travel in an orbital fashion as the wave passes. the water does not necessarily experience much horizontal movement. Direction of wave motion AB Wavelength Height Still water level Crest Trough Frequency: Number of wave crests passing point A or point B each second Orbital path of individual water molecule at water surface Period: Time required for wave crest at point A to reach point B Direction of wave motion Wave-length Still water level Crest Trough Crest 1/2 wave- length depth The orbital motion of water particles in a wave extends to a depth of half of the wavelength. Wind Generated Waves Wind strength Duration Fetch Fully developed sea waves cannot get any bigger from the same wind conditions ~three days of constant wind
