Longitudinal waves travel in the form of……..
a) compression and rarefaction
b) compression only
c) crest and trough
d) rarefaction only
Explanation:Longitudinal waves are waves in which the vibration of the medium is parallel ("along") to the direction the wave travels and displacement of the medium is in the same (or opposite) direction of the wave propagation.
