Question

The intensity of sound
with distance because the
of a sound wave spreads out as the sound travels.

Answer 1

The intensity of sound decreases with distance because the energy of a sound wave spreads out as the sound travels. As the sound wave propagates, its energy is distributed over a larger area, leading to a decrease in intensity (which is defined as power per unit area). This phenomenon can be explained mathematically by the inverse square law, which states that the intensity of a point source of sound is inversely proportional to the square of the distance from the source. Thus, as you move further away from the source of the sound, the intensity decreases significantly.
