- Electromagnetic waves are created by a fusion of electric and magnetic fields. The light you see, the colours around you are visible because of electromagnetic waves.
- One interesting property here is that unlike mechanical waves, electromagnetic waves do not need a medium to travel. All electromagnetic waves travel through a vacuum at the same speed, 299,792,458 ms-1.
Following are the different types of electromagnetic waves:
- Microwaves
- X-ray
- Radio waves
- Ultraviolet waves
