Unformatted text preview: pret this parameter physically, i.e., what does it mean if it is small or large? 3. Review the deep water equations derived in class. Then, describe the gravity surface waves with viscosity. Assume wavelike solutions, e.g. η = Re { η e i ( kxωt ) } , where, η is a complex amplitude, and the frequency ω must be assumed complex. Do the disturbances grow or decay in time? Is this physically reasonable? Verify that the phase speed reduces to the expected value in the limit ν → 0. 1...
