Electromagnetic Waves (EM)

By Jack Crocco

What kind of disturbance creates an EM wave?

Electromagnetic waves are produced from a vibrating electric charge.

What are two ways that EM waves are different from mechanical waves?

  1. EM waves can travel through vacuums but mechanical waves have to travel through mediums. (EM waves travel the same speed in vacuums)
  2. EM waves are caused by the magnetic and electric fields while mechanical waves are caused by wave amplitude.
