Ocean Wavelength Equation:
From: | To: |
Ocean wavelength (λ) is the distance between two successive wave crests or troughs in deep water waves. It is a fundamental property that determines many wave characteristics and behaviors.
The calculator uses the deep water wavelength equation:
Where:
Explanation: This equation applies to deep water waves where water depth is greater than half the wavelength. The relationship shows that wavelength increases with the square of the wave period.
Details: Wavelength calculation is crucial for maritime navigation, coastal engineering, offshore operations, and understanding wave energy distribution. It helps predict wave behavior, interference patterns, and potential impacts on marine structures.
Tips: Enter the wave period in seconds. The period must be a positive value greater than zero. The calculator assumes standard gravity (9.81 m/s²) and deep water conditions.
Q1: What defines "deep water" for this equation?
A: Deep water conditions exist when water depth is greater than half the wavelength (d > λ/2). In shallower water, different equations apply.
Q2: How does wavelength relate to wave speed?
A: In deep water, wave speed (c) = λ/T = gT/(2π). Wavelength and wave speed both increase with wave period.
Q3: What are typical ocean wavelength values?
A: Ocean wavelengths typically range from 10-200 meters for wind waves, up to 400+ meters for swell waves, and can exceed 1000 meters for tsunamis.
Q4: Does this equation work for all wave types?
A: This specific equation applies only to surface gravity waves in deep water. Different equations are needed for shallow water waves, capillary waves, or other wave types.
Q5: How accurate is this calculation?
A: The calculation is mathematically exact for the idealized deep water case. Real-world accuracy depends on how well conditions match the deep water assumption and measurement precision of the wave period.
