Question

which statement below is true
1 sound waves can propagate as longitude all transverse waves, depending on the transmitting medium
2 sound waves are transverse waves and they propagate perpendicular to the the transmitting medium
3 sound waves are longitudinal waves and they propagate parallel to the transmitting medium
4 sound waves can propagate as longitudinal or transverse waves, depending on the temperature​

Answer 1

Answer:

3

Explanation:

Answer 2

Answer:

(3) Sound waves are longitudinal waves and they propagate parallel to the transmitting medium

Explanation:

A Sound wave is defined as a longitudinal wave because of productio of compressions and rarefactions within the air.

The air particles vibrate parallel to the propagation direction.

When vibration of the medium travelling along or parallels the direction of the wave is termed as longitudinal wave.
