A type of wave that can travel through empty space as well as through matter is electromagnetic wave.
Mechanical waves must use matter as a medium, they displace the matter in space. Examples of mechanical waves are sound waves (must go through gas (air) which is matter), ocea â¦ n waves (must go through liquid (water) which is matter, and earthquakes (must go through solid (earth) which is matter. mechanical wave is a wave that needs a medium (type of substance such as gas, liquid or solid) to travel through. Transverse â¦ waves move the medium perpendicular to the energy.
