Radio waves

Radio waves are a part of the electromagnetic spectrum.[1] They typically defined as having wavelengths longer than about a centimetre, though this value depend on the definition. Therefore, radio waves have the longest wavelength and lowest energy of any type of electromagnetic radiation. They are generally used for communication.
