According to the caption below the vertical cross-sections in Figure 6A-1, a surface wave behaves as a deep-water wave if the water depth is greater than ______ its wavelength. a.1/2 b.1/20th c.1/50th
According to the caption below the vertical cross-sections in Figure 6A-1, a surface wave behaves as a deep-water wave if the water depth is greater than ______ its wavelength.
a.1/2
b.1/20th
c.1/50th
As ocean surface waves entering the water of decreasing depth begin to “feel” the presence of the bottom, the character of the waves is altered. The intermediate vertical cross-section in Figure 6A-1, called a transitional wave, shows that the vertical displacements of water parcels follow oval paths which become smaller and more oval-shaped with increasing depth until just above the ocean bottom, the water particle motion is essentially ______.
a.only up and down
b.only horizontally back and forth
c.both up and down, and back and forth
To progress as a shallow-water wave type, as seen in the vertical cross-section on the right in Figure 6A-1, the caption below the cross-section indicates the water depth must be less than ______ its wavelength.
a.1/2
b.1/20th
c.1/50th
