Information, such as sound, is carried by systematically changing (modulating) some property of the radiated waves, such as their amplitude, frequency, phase, or pulse width. When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor. The information in the waves can be extracted and transformed back into its original form.
Hope this helps from scottadroid :D
A text message is a specially formatted digital message that is created in a cell phone and transmitted to a cell tower using radio waves. The message is routed through the network, in much the same way that a voice communication is, and it is ultimately sent to the recipient's phone, again, using radio waves.
Radio waves.
Pagers work by using radio waves. Messages are sent via touch-tone phone, where the person sending the message types a text using their number key pad. The message is then displayed on the pager's screen.
the radio waves be improved by using the bigger signals
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.

astronomy using radio waves, rather than visible light. visible light and radio waves are essentially the same, only radio waves have a much longer wavelength. not everything emits light in the visible band, many otherwise invisible objects can only be detected using extreme wavelengths.
Radio waves, infrared, and microwaves are examples of electromagnetic waves.

Two words: radio waves.
There are no such glasses in existence.
