Q. Illustrate what two properties of electromagnetic waves are used to attach info to radio signals?
Answer:-
By changing the amplitude of a radio wave you can encode information that is how AM-radio works. By changing the frequency (and hence its wavelength) of a radio wave you can as well encode information that is how FM radio works.
