The 'wave length' in deep water is related to wave period T by:
Choose the correct answer
L0 = T (linear)
L0 = gT²/(2π) ≈ 1.56T² — deep water wavelength proportional to T²
L0 = T²/g
L0 = constant regardless of period
Correct Answer
B. L0 = gT²/(2π) ≈ 1.56T² — deep water wavelength proportional to T²

Airy (linear) wave theory: deep water wavelength L0 = gT²/(2π) ≈ 1.56T² (m). Wave period T (seconds) related to wave length L and wave speed C: C = L/T = √(gL/2π) for deep water. In shallow water: C = √(gd) (independent of T). At intermediate depth: L = (gT²/2π)tanh(2πd/L) (implicit). Design wave: significant wave height Hs, peak period Tp from wave spectrum analysis.
