What factor significantly distinguishes deep waves from other types of waves?

• A. Restoring force of surface tension
• B. Wavelength is less than 1.73 cm
• C. Water depth greater than 1/2 wavelength
• D. Wave height less than 3 meters

Answer: (C)

Deep waves are defined by their interaction with the ocean floor and the characteristics of the water column above them. What significantly distinguishes deep waves from other types of waves is that the water depth is greater than half of the wavelength. In deep water, waves can propagate without experiencing friction or interference from the ocean bottom, allowing them to maintain their energy and form over long distances. The depth criterion reflects the fact that the orbital motion of water particles becomes confined and diminishes with depth; hence, if the water depth is more than half the wavelength, the wave is considered a deep-water wave. Surfaces waves, on the other hand, interact with the bottom when water depth is less than half of the wavelength, leading to changes in wave speed and height. This specific relationship between water depth and wavelength is essential in differentiating deep-water waves from shallow-water waves, where the dynamics and behavior of the waves are very different. This foundational understanding is crucial in oceanography as it impacts wave behavior, energy distribution, and the resultant forces acting on coastal environments and marine activities.
