  1. Shallow water waves:Wavelength long relative to water depth Deep water waves:Wavelength short relative to water depth Phase speed depends on wavelength Phase speed depends on depth of water column, not on wavelength! Thus all shallow-water waves propagate at the same speed in water of depth h

  2. Wavelength: 2l Period: T Phase speed: 2l/T If SWW, then 2l/T=(gh) Solving for the period, we get T=2l/(gh) Wavelength: 4l Period: T Phase speed: 4l/T If SWW, then 4l/T=(gh) Solving for the period, we get T=4l/(gh) l=L/4

  3. The Bay of Fundy is about 270 Km long and has an average depth of roughly 60m. Are these dimensions consistent with a resonant behavior of the semi-diurnal tides? T=4l/(gh) = 4 x 270 x 1000 / (9.8 x 60) = = 44,540 seconds = 12.38 hours which is close to the M2 period of 12.42 hours (or N2=12.66 hours, S2=12 hours)
