How to Evaluate Wave Amplitude?

Wave Amplitude evaluator uses Wave Amplitude = Wave Height/2 to evaluate the Wave Amplitude, The Wave Amplitude formula is defined as the measurement of the vertical distance of the wave from the average. Wave Amplitude is the same for linear or small amplitude wave, the highest of the crest above the still-water level (SWL) and distance of the trough below the SWL. Wave Amplitude is denoted by a symbol.

How to evaluate Wave Amplitude using this online evaluator? To use this online evaluator for Wave Amplitude, enter Wave Height (H) and hit the calculate button.
