Unformatted text preview: λ >> d . (c) Tsunamis, produced by large earthquakes or meteor impacts, qual-ify as “shallow water” waves even in the deepest parts of the ocean. Consider a tsunami with a 50 km wavelength and amplitude 3 m travelling in water with a depth of 4 km. Determine the speed and period of the wave. (d) The tsunami encounters increasingly shallow water as it approaches a coastline. When the water depth is 30 m, determine the speed, wavelength, and amplitude of the wave. (Use conservation of en-ergy. What is the period under these circumstances?) 1...
