Electromagnetic (EM) waves are a family of different types of waves that have some specific properties in common;

  • they all propagate (travel) at the same speed
  • they are all transverse waves
  • they can all propagate through free space without the need for any medium

The most common examples of EM wave are the various colours of visible light. Other examples are;

  • radio waves
  • microwaves
  • infra-red
  • ultra-violet light
  • x-rays
  • gamma rays

We will discuss the properties, uses and dangers of these different types of EM waves but for now I have written a short introduction to the discovery of the first invisible EM waves, which you can read here.
