Why are sound waves considered transverse waves?

Sound waves are not transversal waves, they are longitudianal waves. Their wave motion (a preassure difference) is parallel to the propagation direction, which means they are longitudinal. read more

” Well, they are only called longitudinal when they are longitudinal. Perhaps the person you spoke with was only using sound as an example of an L-wave. Perhaps they are unaware that sound propagates in numerous ways. read more

Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves as depicted in the animation below. read more

We all know that sound is a longitudinal wave but in some books, I have found that sound travels in the form of both longitudinal and transverse waves while passing through rocks. read more
