Radio waves are most commonly used in communication due to their ability to travel long distances and penetrate obstacles easily. They are used for various purposes such as radio broadcasting, cell phone signals, Wi-Fi networks, and satellite communication.
Radio waves have the longest wavelength among electromagnetic waves. They have wavelengths ranging from about 1 millimeter to over 100 kilometers. Radio waves are used for various communication technologies, including radio broadcasting and cellular networks.
The type of electromagnetic wave used for TVs is radio waves. Specifically, TV signals are carried on radio frequencies within the electromagnetic spectrum.
Radio waves are electromagnetic radiation with very long wavelengths, ranging from about 1 millimeter to over 100 kilometers. They are used for various communication purposes, such as broadcasting, cellular networks, and WiFi.
Electromagnetic waves, specifically radio waves, are commonly used to communicate with satellites. These waves travel through the vacuum of space and can transmit information over long distances.

It is a device which used for taking and reasoning in between two persons is called cellular telephone networks
Telecommunication over telephone networks.
In order to used this networks in conjunction with other apparatus in telephone system they must be provide efficient transmission !
Radio waves are most commonly used in communication due to their ability to travel long distances and penetrate obstacles easily. They are used for various purposes such as radio broadcasting, cell phone signals, Wi-Fi networks, and satellite communication.
it just reflects waves radiated from the earth like telephone radiations and this is the thing that is used in satellites!
A telephone is an instrument that sends voices using electricity. Sound waves are converted into electrical signals, transmitted through wires or wireless networks, and then converted back into sound at the receiving end, allowing people to communicate over long distances in real time.
Information is usually transmitted in terms of either radio waves or acoustic energy in a telephone. Machines such as the fax are usually used.
Radio waves are used to transmit signals from a radio station, and you can receive the signals with a radio, and hear them as sound such as speech or music. The long wavelength of radio waves makes them a suitable medium for transmitting over a large range. it is also use in agriculture...... it is used to diagnose different diseases
