Mainly the fact that such waves can travel through empty space.
A cell 'phone does not transmit sound. It transmits electromagnetic radiation. Sound is converted to and from an electromagnetic signal by the microphone and speaker.
the property is diffusion
No, only nucleic acids store and transmit hereditary information.
sometimes only partially transmit information, depending on signal strength.
Some forms of electromagnetic radiation that can pass through glass are x-rays,gamma rays,ordinary light,microwaves,infrared and radio waves.
Well, when you transmit something as an electromagnetic wave, it is no longer an electric current, since an electromagnetic wave doesn't involve movement of charges. However, you can convert electrical energy into an electromagnetic wave, transfer that, and then convert it back to an electric current at the receiving end.
Electromagnetic energy
because electromagnetic waves transmit energy without compressing the particles of the medium

Signals
the property is diffusion
morse code
The hearing aids which transmit and detect electromagnetic waves as electromagnetic wave can propagate on the moon.
No, only nucleic acids store and transmit hereditary information.
yes it is possible
communication warks on the information gap principle. transmission of information is possible only if there is a gap between the information which the sender intends to transmit on any given topic, and the information that the receiver already possesses on that topic.
