19-Sound travels in which kind of wave?1 pointLongitudinal wavesTransverse waves

Answer

Sound travels in longitudinal waves.

In a longitudinal wave, the particles of the medium through which the sound travels vibrate parallel to the direction of the wave's propagation. This means that as sound moves through a medium (like air, water, or solids), areas of compression and rarefaction are formed as particles move closer together and then further apart.

Transverse waves, on the other hand, involve particle movement perpendicular to the direction of the wave, as seen in waves on a string or electromagnetic waves like light. Since sound requires a medium to travel and the particle motion is aligned with the direction of the wave, it is classified as a longitudinal wave.
