Question

5 multiple choice 1 point how does sound usually travel? an object vibrates, and those vibrations carry air in all directions as transverse waves. b. an object vibrates, and those vibrations carry air in one direction as longitudinal waves d. an object vibrates, and those vibrations travel through the air in all directions as longitudinal waves. a. an object vibrates, and those vibrations travel through the air in one direction as transverse waves.

Explanation:

Sound is produced when an object vibrates. The vibrations travel through a medium (in this case, air) as longitudinal waves. Longitudinal waves have particle - motion parallel to the direction of wave propagation. Also, sound waves usually spread out in all directions from the source (the vibrating object), not just in one direction. Transverse waves have particle - motion perpendicular to the direction of wave propagation and sound is not a transverse wave in air.

Answer:

D. An object vibrates, and those vibrations travel through the air in all directions as longitudinal waves.
