Want this question answered?
Mechanical waves are waves that need medium to propagate so they don`t travel through vacuum but through solid , liquid or gas.
Sound waves cannot propagate in vacuum. Air is needed for sound waves to travel and there is no air in vacuum.
Sound being a longitudinal mechanical wave needs a medium to propagate. In a vacuum (like the outer space), there is no matter to act as the medium and thus sound waves can not propagate.

No, eletromagnetic waves propagate in two planes (eletro-magnetic) and can propagate in a vacuum. Water waves, on the other hand, are dependant on matter to transfer energy, making it a mechanical wave, not an eletromagnetic one.
Those waves which required medium for propagation are called mechanical waves. e.g sound waves,they need medium i.e solid liquid or gas ,to propagate. They cant travel through vacuum. hope u understand that!!

Mechanical waves can't pass through a vacuum. Mechanical waves need something to pass through. Space is generally considered a vacuum, with nothing in it to transmit a mechanical wave.
Light waves propagate best through vacuum, or "nothing." Light waves also propagate at slower speeds through denser materials, such as air, glass, and clear water.
Here are some differences between mechanical and electromagnetic waves.Mechanical waves can be either transverse or longitudinal. Electromagnetic waves are only transverse waves.Mechanical waves require a material medium to propagate. Thy can only travel in solids, liquids and gases. Electromagnetic waves do not require any medium. They can travel in vacuum also.Electromagnetic waves travel at the speed of light. Mechanical waves travel at much slower speeds.Mechanical waves propagate by the vibration of molecules of the medium. Electromagnetic waves travel by the oscillations of the electrical and magnetic vectors of a photon.
Sound waves do not propagate in a vacuum, since they are basically vibrations (compressions and rarefactions) in a medium, and in a vacuum there is no matter to vibrate.
The waves that propagate through particles of a medium are mechanical waves (aka waves of vibration).
