What is the distance between identical points on adjacent wave cycles?

• A. Wavelength
• B. Period
• C. Amplitude
• D. Frequency

Answer: (A)

The distance between identical points on adjacent wave cycles is the wavelength—that spatial distance over which the wave’s pattern repeats. It can be thought of as crest to crest or trough to trough spacing along the medium, showing the wave’s spatial period. Period is the time for one full cycle, measured in seconds, not a distance. Frequency is how many cycles occur each second, measured in hertz. Amplitude is how tall the wave is—the maximum displacement from rest. So this distance between identical points on successive cycles specifically defines the wavelength.
