Document Summary
Wave generation: disturbing force causes waves to form, wind blowing across ocean surface, interface of fluids with different densities, air ocean interface. Ocean waves: air air interface. Atmospheric waves: water water interface. Internal waves: associated with pycnocline, larger than surface waves, caused by tides, turbidity currents, winds, ships, under the surface of the water. Progressive waves: oscillate uniformly and progress without breaking, longitudinal, transverse, orbital. Longitudinal waves (push pull: compression and decompression as they travel, like a spring, carry sound and energy through any medium, energy released and transferred, like clapping, can travel great distances. Transverse waves (ide to side: energy travel straight angles to direction of moving particles, stable transferors wave, only transfer through stable forms, rope. Wind-generated waves in shallow near shore areas. Transitional waves: characteristics of both deep and shallow-water waves, celerity depends on both water depth and wavelength.
