1. What is Wave Amplitude?

Wave Amplitude is a measurement of the vertical distance of the wave from the average. It represents half of the wave height, which is the difference between the elevations of a crest and a neighboring trough.

2. How Does the Calculator Work?

The calculator uses the wave amplitude formula:

Where:

• \( a \) — Wave Amplitude (m)
• \( H \) — Wave Height (m)

Explanation: The amplitude is exactly half of the total wave height, representing the maximum displacement from the equilibrium position.

3. Importance of Wave Amplitude Calculation

Details: Wave amplitude is crucial in oceanography, coastal engineering, and wave energy studies. It helps determine wave energy, predict coastal erosion, and design marine structures.

4. Using the Calculator

Tips: Enter wave height in meters. The value must be positive and greater than zero to calculate the corresponding amplitude.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between wave height and wave amplitude?
A: Wave height is the total vertical distance between crest and trough, while amplitude is half of that value, representing the maximum displacement from the mean water level.

Q2: How is wave amplitude related to wave energy?
A: Wave energy is proportional to the square of the wave amplitude. Doubling the amplitude quadruples the wave energy.

Q3: Can this formula be used for all types of waves?
A: This simple relationship applies to regular sinusoidal waves. For irregular waves or waves with different profiles, more complex calculations may be needed.

Q4: What are typical wave amplitude values in oceans?
A: Ocean wave amplitudes typically range from a few centimeters to several meters, with extreme storm waves reaching amplitudes of 15 meters or more.

Q5: How is wave amplitude measured in practice?
A: Wave amplitude can be measured using wave buoys, pressure sensors, radar systems, or satellite altimetry, depending on the application and required accuracy.
