Amechanical wave is created when a medium or moves back and forth or up and down

A mechanical wave is created when a medium allows the transfer of energy, or moves back and forth or up and down. It  is a wave that is a vibration in matter, transferring energy through a material. While waves can move over long distances, the movement of the medium of transmission is limited. Hope this answers the question.

That's  a project for you to do. btw your teacher probably uses a plagiarism detector and if you do copy anything on this site she/ he will find out and instead of getting a good  or bad grade you'll  get a 0 no exceptions, and they'll  probably call ur parents. so do some research ask friends and fam to you.
