A bell is rung. What best describes the density of air around the bell? The air density does not change. The air density increas
es and then returns to normal levels. The air density decreases and then returns to normal levels. The air density increases and decreases repeatedly before returning to normal.
I think the closest possible answer to this question is The air density increases and decreases repeatedly before returning to normal.Thank you for your question. Please don't hesitate to ask in Brainly your queries.
The correct answer to the question is : D). The air density increases and decreases repeatedly before returning to normal
EXPLANATION:
Before coming into any conclusion, first we have to understand sound wave.
A sound wave is a longitudinal wave in which the vibration of particles are parallel to the direction of wave propagation. It moves in the form of compression and rarefaction.
Compression is the high pressure region where particles are closely aggregated. Rarefaction is the region of low pressure where particles of the medium are not so close to each other just like compression.
Hence, the correct statement will be that the air density increases and decreases repeatedly before returning to normal .
