The word comes from Latin vibrationem]]> 2017-11-14 16:34:30 UTC https://padlet.com/3049561/bx4piuv8xqy3/wish/206816916 3049561 https://padlet.com/3049561/bx4piuv8xqy3/wish/206817632 A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position]]> 2017-11-14 16:35:44 UTC https://padlet.com/3049561/bx4piuv8xqy3/wish/206817632 3049561 https://padlet.com/3049561/bx4piuv8xqy3/wish/206818652 a wave vibrating at right angles to the direction of its propagation]]> 2017-11-14 16:37:14 UTC https://padlet.com/3049561/bx4piuv8xqy3/wish/206818652 3049561 https://padlet.com/3049561/bx4piuv8xqy3/wish/206819588 A substance that makes possible the transfer of energy from one location to another, especially through waves. For example, matter of sufficient density can be a medium for sound waves, which transfer mechanical energy.
