All mechanical waves must have a medium through which to propagate. The medium may be an matter in any phase - solid, liquid, gas, etc. The waves propagate in either transversely or longitudinally modes. Transverse propagation is perpendicular to the direction of motion; some examples of transverse waves are things like a flag rippling in the wind or the waves of a ribbon or curtain moving up and down along the surface. Longitudinal waves move parallel to the direction of propagation as compressions and rarefactions (stretching). Some examples of these waves are sound waves, and compression waves in springs. Some waves, like water waves, may show both transverse and longitudinal character.

Which type of wave must have a medium in order to travel?
Mechanical waves require a medium in order to travel. These waves propagate by transferring energy through a medium by causing particles in the medium to vibrate. Some examples of mechanical waves include sound waves and seismic waves.
Which type of waves require matter in order to travel?
Mechanical waves require matter in order to travel. These waves propagate through a medium such as water, air, or a solid material by transferring energy through the vibration of particles in the medium. Examples of mechanical waves include sound waves and seismic waves.
What is one major difference between electromagnetic waves and mechanical waves?
One major difference is the medium of propagation. Electromagnetic waves do not require a medium (can travel through vacuum) while mechanical waves require a medium (such as air, water, or solid material) in order to propagate.
How are electromagnetic waves different from all other waves, specifically mechanical waves?
Electromagnetic waves do not require a medium to travel through, unlike mechanical waves which do. Additionally, electromagnetic waves can travel through a vacuum, while mechanical waves cannot.
Can mechanical waves traves through empty space?
No, mechanical waves require a medium (such as air, water, or solids) to travel through. In empty space, there is no medium for mechanical waves to propagate, so they cannot travel through vacuum. Examples of mechanical waves include sound waves and seismic waves.
