What is another word for longitudinal wave?
Pronunciation: [lˈɒnd͡ʒɪtjˌuːdɪnə͡l wˈe͡ɪv] (IPA) 
A longitudinal wave is a type of wave in which the particles of the medium vibrate parallel to the direction of the wave's propagation. However, there are a few synonyms to describe this type of wave. One of the most common synonyms is compression wave, as this describes how the particles of the medium are pushed together and then pulled apart as the wave passes through. Another synonym is pressure wave, as these waves create changes in pressure within the medium as they travel through it. Finally, sound waves can also be considered a synonym for longitudinal waves, as they are a type of wave that travels through air or water by compressing and releasing the particles in the medium.
