In the electromagnetic spectrum, the electromagnetic wave with the lowest frequency is the radio wave. Radio waves have frequencies ranging from 30 Hz to 3 GHz. Radio waves are usually produced through LC modulation (tuned circuits), and carry information through modulation (usually through AM or FM)

Answer:

Radio waves

Explanation:

The electromagnetic spectrum includes all different types of waves, which are usually classified depending on their frequency. Ordering them from the highest frequency to the lowest frequency, they are:

- Gamma rays

- X-rays

- Ultraviolet

- Visible light

- Infrared radiation

- Microwaves

- Radio waves

Radio waves are the electromagnetic waves with lowest frequency, their frequency is lower than 300 GHz ([tex]3\cdot 10^{11} Hz[/tex]) and therefore they are the electromagnetic waves with lowest energy (in fact, the energy of an electromagnetic wave is proportional to its frequency). They are generally used for radio and telecommunications since this type of waves can travel up to long distances.
