Question
A trough represents ______.
- Maximum compression
- Minimum compression
- Minimum rarefaction
- None of the above
Hint:
Maximum rarefaction= minimum compression
The correct answer is: Minimum compression
- The rarefaction is the part of the wave that has the lowest density and lowest pressure.
- Maximum rarefaction= minimum compression.
- Therefore, it is represented by a trough.
