Which term is the highest part of a progressive wave above the average water level?

Which term is the highest part of a progressive wave above the average water level?

• A. Wave
• B. Wave Crest
• C. Wave Height
• D. Wave Diffraction

Answer: (B)

The highest point of a progressive wave above the average water level is called the crest. The crest is the peak of the wave as it travels along the surface, sitting above the mean water level. Wave height, by contrast, is the vertical distance from the crest to the trough, not the top point itself. Wave is a general disturbance, and diffraction describes how waves bend around obstacles, not the highest point. So the crest is the correct term.
