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:

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.

The characteristics of radio waves are determined by the frequencies. The short waves, long waves and shorter wavelengths have different features.

The International Telecommunications Union or ITU is the governing body, which regulates the law of the usage of artificial generation of radio waves. The law is used to prevent any interference among the users.

In 1867, James Clerk Maxwell was a Scottish mathematical physicist who first created a prediction related to the presence of radio waves in his mathematical work.

The first practical radio transmitters and receivers were developed by Guglielmo Marconi. In the mid 1890s, people began to employ the radio waves for communication.

The permittivity as well as the permeability of an object is very important to notice when the radio waves pass an object.
