Which statement is NOT one of the four parameters used to describe a single cycle?

• A. Period
• B. Wavelength
• C. Amplitude
• D. Propulsion speed

Answer: (C)

Describing a single cycle focuses on how often and how far the cycle repeats as the wave moves. The period tells how long one cycle takes, the wavelength tells how far the wave travels in one cycle, and the propagation speed describes how fast the wavefront moves. Frequency, which is the reciprocal of the period, is another way to express the same timing aspect. These describe the cycle’s timing and spatial repetition. Amplitude measures how tall the wave is—its displacement magnitude—not the cadence or spacing of the cycle, so it isn’t part of the standard set used to describe a single cycle.
