3. With the compressions and rarefactions, what you were
Able to produce is called a longitudinal wave.
Longitudinal waves are waves that are usually created by pu
lling and pushing the
material or medium just like in the slinky (Figure 6). Alternat
ing compressions and
rarefactions are observed. These compressions and rarefacti
ons move along with
the direction of the pushing and pulling activity of the mater
ial or medium. Thus, the
wave moves parallel to the motion of material or the particle
s of the medium. This is
known as a longitudinal wave.
