AM and FM radios are the common type of radios we find in our homes. They communicate by means of radio waves - hence the name - which is the lowest frequency of the electromagnetic spectrum. Electromagnetic waves are much similar to sound waves when considering its wave character, but differ in the aspect that it is made up of electric and magnetic vectors, and not mechanical attributes. One more point; radio waves have two aspects we change in order to communicate or send information. They are its amplitude and frequency
