1. What is Wave Energy?

Wave energy refers to the total energy contained in ocean waves, which is a combination of potential and kinetic energy. It's a significant renewable energy source that can be harnessed for electricity generation.

2. How Does the Calculator Work?

The calculator uses the wave energy equation:

Where:

• \( E \) — Wave energy per unit crest length (J/m)
• \( \rho \) — Water density (kg/m³)
• \( g \) — Gravitational acceleration (m/s²)
• \( H \) — Wave height (m)
• \( \lambda \) — Wavelength (m)

Explanation: The equation calculates the total energy contained in a wave, considering the water density, gravitational force, wave height squared, and wavelength.

3. Importance of Wave Energy Calculation

Details: Accurate wave energy calculation is crucial for ocean engineering, coastal protection, renewable energy assessment, and understanding wave dynamics in marine environments.

4. Using the Calculator

Tips: Enter water density in kg/m³ (typically 1025 for seawater), gravitational acceleration in m/s² (9.81), wave height in meters, and wavelength in meters. All values must be positive.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical density value for seawater?
A: Seawater density is typically around 1025 kg/m³, but it can vary with temperature and salinity.

Q2: Why is wave height squared in the equation?
A: Wave energy is proportional to the square of wave height because both potential and kinetic energy components depend on wave amplitude squared.

Q3: What units should I use for the inputs?
A: Use SI units: kg/m³ for density, m/s² for gravity, meters for wave height, and meters for wavelength.

Q4: Can this formula be used for all types of waves?
A: This formula is most accurate for linear waves in deep water. For shallow water or nonlinear waves, additional corrections may be needed.

Q5: How is wave energy related to wave power?
A: Wave power is the rate at which wave energy is transmitted, calculated as wave energy multiplied by wave group velocity.
