The EM spectrum:
The electromagnetic spectrum consists of a group of radiations that all travel at the speed of light ().
Electromagnetic waves carry energy. The waves consist of transverse vibrations in electrical and magnetic fields, not vibrating particles. Electromagnetic waves do not need matter to travel through - they can travel through empty space (a vacuum).
In a vacuum, all electromagnetic waves travel at - the fastest speed possible. When electromagnetic waves…
