Electromagetic Waves

By: Aidan Magee

How are EM waves created?

Electromagnetic waves are created when there is a changing (disturbance) in a magnetic field. When a field changes it creates electromagnetic wave(s).

How is an EM wave different from a Mechanical wave?

EM and Mechanical waves are different in many ways. For example mechanical waves need a medium to travel through and EM waves do not. Also mechanical waves are produced by amplitude and EM waves are produced by charged particles.
