Question
The high-pressure regions formed when a sound wave propagates through a medium ____.
- Are called compressions
- Contain densely packed particles
- Are formed alternatively with low pressure regions
- All of the above
Hint:
The high-pressure regions are formed when a sound wave propagates through a medium that has dense particles with Compressions
The correct answer is: All of the above
- The region in a sound wave, with higher pressure and density, is called compression.
- Sound wave consists of an alternating pattern of high pressure (compressions) and low pressure (rarefactions) regions traveling through the medium.
- So, the correct option is d.
