To send information with a radio wave, you changesome characteristic of the
radio wave, according to some pattern that the people on both ends agree on.
For example ... you can turn the radio wave on and off, with long and short bursts,
and long and short spaces between them. You can have a different pattern for each
letter of the alphabet, and you can spell out words and sentences with the patterns.
Now, anybody who can receive your radio waves, and knows the patterns you're using,
can understand what you're saying.
You can call your system: "Morse Code".
I don't think they do because the current goes through the wire whereas on a mobile phone it is radio waves through the air.
Some benefits of radio waves are: You can use many devices such as tv's,cell phone's and radio's without a cord, they can send signals easily to your device and they have the longest wavelength among the electromagnetic spectrum.
Radio waves are a type of electromagnetic radiation similar to visible light. If there were 2 light sources with different color light you would not have any problem seeing both colors. It is the same with radio waves on different wavelengths.
Yes, just go to their fan-mail website and send them an email soon their mail letter will come back to you
No, a radio wave is not a mechanical wave. A radio wave is a form of electromagnetic (EM) energy, and it does not require a medium through which to travel like a mechanical wave does. Radio waves can travel through the vacuum of space. Let's contrast that with a mechanical wave.A mechanical wave involves the transfer of mechanical energy into and through a medium. Sound waves (which travel through air) and water waves (which move through water) are mechanical waves. They cannot travel without a medium through which to move.
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
to send radio waves through the air to make the radio work

Yes - the handset and the base-station send radio waves to each other to maintain the conversation.
The troposphere... It acts like a gigantic mirror - reflecting radio waves back to Earth.

Radio Waves
electromagnetic radiation in the microwave range some times cell phones use 50% uses and 50%health prombles overtimes don t uses
It is receiving the waves from radio or television stations who send them troughout sending devices. A radio station for example will have a tower which sends these waves up to a certain distance radius.
Wireless is the older, British term for radio. It is a short form of the phrase wireless telegraphy, because radios could send messages without the use of wires connecting the sender to the receiver. The term radio is short for radio-telegraphy, indicating that a message was sent in the form of radiation (what we now call radio waves).
