This is from Wikipedia:
1. What is really meant by "self-propagating", how it works?
2. How many electric and magnetic fields are in one wave?
3. What is the strength of those electric and magnetic fields?
4. What does -q and +q represent in the above diagram?
5. Why would electric and magnetic fields oscillate?

The electromagnetic waves that compose electromagnetic radiation can be imagined as a self-propagating transverse oscillating wave of electric and magnetic fields.
