7 key features of Radio waves

1) used for communication e.g. television and radio 2) transmitted easily through air 3) do not cause damage if absorbed by the human body 4) can be reflected to change their direction 5) can be produced by oscillations in electrical circuits 6) When radio waves are absorbed by a conductor, they create an alternating current the electrical current has the same frequency as the radio waves 7) Information is coded into the wave before transmission, which can then be decoded when the wave is received
