Answer :
Final answer:
As sound waves travel away from their source, their intensity decreases due to the spreading of energy over a larger area. Properties such as wavelength, speed, and pitch do not change with distance. Thus, intensity is the property that decreases as you get farther away from the sound source.
Explanation:
Understanding Sound Wave Properties
Sound waves, as they propagate from their source, exhibit various properties that change with distance. Among these properties, intensity is the one that decreases as you move farther away from the sound source. This is because as sound waves travel outward, they spread over a larger area, leading to a reduction in their energy per unit area, which is what we perceive as intensity.
The distance from the source can be visualized through a spherical spreading of the sound, where the energy diminishes with increased distance due to the geometric nature of wave propagation. In contrast, other properties like wavelength, speed, and pitch generally remain unchanged despite the distance.
Conclusion
Therefore, the correct answer to the question is:
- A. Intensity
