Mechanical Waves

[SuperSaiyan3]

What is a mechanical wave? Just like sound waves or water waves or BOTH?

Do they only transport energy and not mass?

 

[matth87]

Mechanical waves can be transverse or longitudinal.

Waves only transport energy, there is no net transport of the medium in which they propagate.

 

[Bernoull]

I second the post above. The mechanical part is that wave propagation requires physical disturbance of the medium. For sound in air, the air molecules undergo compressions and rarefactions..
