Which term is used for a basic progressive wave where the wave form travels in one direction along the surface?

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

Answer: (A)

A basic progressive wave is a wave form that travels in one direction along the surface, carrying energy as it moves. This is what distinguishes it from standing patterns that stay in place. In surface waves, the crests advance along the surface, showing energy transfer through the medium. Seiches are standing waves in a closed basin, so they don’t propagate in one direction. Sea state simply describes the overall roughness and conditions of the sea, not a specific wave type. Orbital wave describes how water particles move in a progressive surface wave (in circular paths near the surface, diminishing with depth) rather than naming the wave itself. So the term that fits is progressive wave.
