Question

what is the best analogy for the motion in a sound wave? a. a guitar string vibrating b. a spring bouncing c. a rope being flicked d. an ocean wave

Explanation:

Sound waves are longitudinal waves, and a guitar - string vibrating produces transverse waves. A spring bouncing is an example of simple harmonic motion similar to the back - and - forth motion in a sound wave. A rope being flicked produces transverse waves. An ocean wave is also a type of surface wave which is different from the motion in a sound wave. The back - and - forth motion of a spring is most analogous to the compression and rarefaction motion in a sound wave.

Answer:

B. A spring bouncing
