Final answer:
Each peak in the waveform corresponds to a different wavelength, which is the length from one peak to the next in the wave.
Step-by-step explanation:
Each peak in the waveform corresponds to a different wavelength. According to the information provided, the amplitude is the height of a wave or, more precisely, the distance from the center line to the top point of the crest or the bottom point of the trough. The wavelength refers to the length of a wave from one peak to the next. However, a waveform can also illustrate the frequency—the number of waves passing by a specific point per second—but each individual peak does not represent a different frequency. In the context of the question, if we are identifying the property that directly corresponds to an individual peak in a waveform, it is the wavelength that's being referred to, not the frequency, amplitude, or phase.
