Highest point of a wave?

Highest point of a wave?

• A. Crest
• B. Trough
• C. Amplitude
• D. Wavelength

Answer: (A)

The highest point of a wave is the crest. As a wave travels, the particles of the medium move up and down from a resting position, and the crest is where this upward displacement is at its maximum. The lowest point is the trough, where the displacement is at its minimum. The height of the wave from the rest position to the crest is called the amplitude, which describes how tall the wave is but not which point is highest. Wavelength is the distance between two successive crests (or troughs). So the crest is the topmost point of the wave.
