The type of wave that needs a medium to travel is a mechanical wave. Mechanical waves, such as sound waves (which can be compression waves), require a medium (solid, liquid, or gas) to propagate. In contrast, light waves (electromagnetic waves) can travel through the vacuum of space and do not require a medium.
