    A wave travels through a medium because
    A wave is an propagation of energy along a medium. Waves need a medium in order for them to travel from one point or another. A wave is a particulate transfer of motion from one point to another. A very good example of the need of a medium is regarding sound. Sound cannot travel through a vacuum. This is because there are no air molecules to transfer the energy of the sound propagation. Hence no sound travels through the vacuum. The particle to particle interaction and vibration results in the transfer of energy in a wave propagation.
