Sound Wave A is moving through a medium that is decreasing in temperature.
Sound Wave B is moving from a liquid to a gas medium.
Which statement can be made about both waves?
A. They will speed up.
B. They will increase the density of their medium.
C. They will slow down.
D. They will decrease the density of their medium.
Answer (1)
Both Sound Wave A and Sound Wave B will slow down as they travel through their respective media. This is due to Sound Wave A encountering lower temperatures, which slows molecular motion, and Sound Wave B transitioning from a faster medium (liquid) to a slower one (gas). Thus, diminishing their overall speed in both cases. ;
