A type of electromagnetic radiation is explained on Interesting Facts about Radio Waves. Compared to the infrared light, the wavelength of electromagnetic radiation is longer in the electromagnetic spectrum. There are several definitions, which state that radio waves have the frequencies at 1 to 3 GHZ for the microwaves. The other ones state that they have the frequencies at 3 kHz to 300 GHz. The wavelength reaches 62 miles or 100 kilometer at 3 kHz and 0.039 inches or 1 mm at 300 GHz. Let us find out other interesting facts about radio waves below:
Interesting Facts about Radio Waves 1: how to generate radio waves
The astronomical objects and lightning may produce the radio waves naturally. The radio waves are similar with other electromagnetic waves for they travel at the speed of light.
Interesting Facts about Radio Waves 2: the usage of artificial production of radio waves
The radio waves are often used for communication satellites, broadcasting, mobile radio communication, computer networks, broadcasting, and radar.
Interesting Facts about Radio Waves 3: how to produce the artificial radio waves
The radio transmitter is applied when people want to generate the radio waves. The radio receivers will receive the waves.
