Short answer

Page 31: Lots of fun! Win valuable prizes!. 1. The source of all wave motion is a A. region of variable high and low pressure. B. movement of matter. C. harmonic

A mechanical wave is a disturbance in matter and cannot travel through a vacuum. Sound, water waves and a vibrating guitar string are all examples of mechanical waves.

An electromagnetic wave is made of vibrating electric and magnetic fields and can travel through a vacuum. Light, radio waves and microwaves are all examples of electromagnetic waves.
