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

How does a text message arrive to the next person?
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.
What energy involved when sending text message?
Radio waves.
How exactly do pager systems work?
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.
How can radio telescopes be improved?
the radio waves be improved by using the bigger signals
Are radio waves a form of sound or light?
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.
What is the palindrome for a detection system using radio waves?
radar
What is radio astromony?
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.
What layer of the atmosphere reflects radio waves?
The ionosphere is the layer of the atmosphere that reflects radio waves. This layer is able to reflect specific frequencies of radio waves back to Earth, allowing for long-distance communication using radio signals.
What is a sentence using the word electromagnetic wave?
Radio waves, infrared, and microwaves are examples of electromagnetic waves.
Is it possible to see the radio waves in the air with special glasses?
There are no such glasses in existence.
How is it possible for astronauts to use the Internet from space?
Two words: radio waves.
How do optical telescopes and radio telescopes gather info about stars?
using radio waves it collects the data.
