Which term describes a standing wave pattern formed by resonance in a basin due to tidal or meteorological forces?

• A. Rogue Wave
• B. Sea State
• C. Progressive Wave
• D. Seiche

Answer: (D)

The concept being tested is standing waves formed in a basin when the water is driven at a periodic frequency that matches the basin’s natural sloshing frequency. When tides or atmospheric changes push and pull the water at the right rate, energy builds up and the basin oscillates as a standing wave with nodes and antinodes. This pattern is called a seiche. Rogue waves are isolated, unusually large waves; sea state refers to overall surface conditions; a progressive wave is a traveling wave that moves energy from one place to another. Seiches can occur in lakes, harbors, or bays and their period depends on the basin’s size, shape, and depth.
