Radio is the wireless tranmission of signals through free space by electromagnetic radiation of a frequency significantly below that of visible light radio frequency range from about 30Khz to 300 GHz. These wawes are called radio wawes.Electromagnetic radiation travels by means of oscillating electrimagnetic fields that pass through the air and the vacumm of space.
Information such as sound is carried by sistematically changing some property of the radiated wawes, such as their amplitude,frequency,phse or pulse width.When radio wawes strike an electrical comductor,the oscillating fields induce analternating current in the cotnductor.The information in he wawes can be extacted and transformed back into its original form.
