Describe a longitudinal wave.
A longitudinal wave has a medium that moves parallel to the wave direction.

Describe the two types of waves that make up mechanical waves
One is a transverse wave-the medium moves perpendicular to the wave direction.
Another is the longitudinal or Compression wave where the medium moves parallel to the wave direction.

Why do we call these waves "Mechanical" waves?
We call them mechanical waves because they need a medium to transfer their energy.
