- 5.As mechanical waves move through a medium, particles of the medium undergo a periodic and repeated vibration about a fixed position.
- A.
True
- B.
False
- 6.Describe how a wave is different than a pulse.
- 7.Mechanical waves propagate or move through a medium because ________.
- A.
The particles of the medium are able to move along the curved wavelike pathway
