The Mystery Of Radio Waves

Radio waves are just a type of electromagnetic radiation. Their frequency ranges between 3 Hz and 1 gigahertz. They are also known to have the longest wavelength in the electromagnetic spectrum, which means their length can range from the size of a football to a planet.

While they are invisible to the eyes, they are paramount in technological communication every day. They are also transformed into sound waves, which are heard as a broadcast.
