Electromagnetic waves are a group of energy waves that are mostly invisible and can travel through empty space.. Waves. What is a wave?. A wave is a disturbance that travels from one location to another location. The traveling disturbance in a wave is carrying energy (NOT matter). Waves that require a medium to travel through are .
