Compressions and rarefactions of sound waves normally travel
A. at reduced frequencies.
B. none of the above
C. in opposite directions.
D. at different speeds.
E. all of the above
Answer (2)
Compressions and rarefactions in sound waves travel as part of the same wave and do not move in opposite directions, at different speeds, or reduced frequencies. They maintain their relationship as they propagate. Therefore, the best answer is "none of the above." ;
The correct answer is "B. none of the above" since compressions and rarefactions in sound waves travel together in the same direction and at the same speed. They are integral parts of the wave and do not move independently. Hence, they do not differ in speed, frequency, or direction of travel.
