Sound wave is a Longitudinal Wave. When Sound Wave travels through air it will create expanding or shrinking column of airs called Rarefraction and RareExpansion.
Best Answer: 1.A mechanical wave is a wave that requires a medium through which to transmit energy. Sound waves, waves in a Slinky, and pressure waves are all examples of this.Sound waves need air molecules in order to exist; the Slinky waves need the Slinky, and the waves in the ocean need the water.nce this initial energy is added, the wave will travel through the medium until all the energy has been transferred. There are three types of mechanical waves. Transverse waves are waves that cause the medium to vibrate at a 90-degree angle to the direction of the wave.
