Radio waves are the waves with lowest frequency and largest wavelength and ofcourse the smallest energy in electromagnetic spectrum. As like other electromagnetic waves they are created by oscillation of charges, and they travel through the air at the speed of light. Radio waves have a frequency range of10 kilo Hz to 100 GHz.

What are radio waves?
Radio waves are a type of electromagnetic radiation, like light or x-rays. Except they have longer wavelengths in the electromagnetic spectrum. The radio waves frequency ranges from as high as 300 GHz down to 3 kHz.
What is the range of radio waves?
Radio waves are a type of electromagnetic radiation with frequencies ranging from 300 GHz to as low as 3 Hz, and wavelengths ranging from 1 millimeter (0.039 inches) to 100 kilometers (62 miles). Similar to all other electromagnetic waves, they travel at the speed of light.
Do radio waves travel at the speed of light?
At 300 GHz, the frequency of radio waves is 1 mm, and at 3 kHz is 100 km. They travel at the speed of light simply like all other electromagnetic speeds of radio waves do.
What has the longest frequency of radio waves?
Bookmark added to your notes. Radio waves are the waves that are a sort of electromagnetic radiation and have a recurrence with the longest frequency of radio waves from high 300 GHz to low as 3 kHz; however, someplace it is characterized as over 3 GHz as microwaves. At 300 GHz, the frequency of radio waves is 1 mm, and at 3 kHz is 100 km.
