Final answer:
For a sound wave, the distance between compression points identifies the 3. wavelength, which is the distance between two consecutive compressions or rarefactions in a longitudinal wave.
Step-by-step explanation:
For a sound wave, the distance between compression points identifies the wavelength. The wavelength is the distance between two consecutive compressions or between two consecutive rarefactions in a longitudinal wave, such as a sound wave. In terms of sound wave characteristics, the amplitude is the distance between the resting position and the maximum displacement of the wave, not the distance between compression points.
The frequency of a wave is the number of waves that pass a specific point per second and is not determined by the distance between compressions. Overall, wavelength, frequency, amplitude, and speed of propagation are vital characteristics of sound waves. In the context of sound waves traveling through a medium like air, the relationship between wavelength and frequency is crucial for understanding the phenomenon of sound and its properties.
