Telephone
If you've ever talked to anyone on a cell phone, or if you've ever used a pair of toy
walkie-talkies, or a bluetooth headset, or a cordless telephone, or Wi-Fi, then
you've used radio waves for two-way communication.
If you've ever used a GPS receiver in the car, or a wireless mouse or keyboard,
or a garage door opener, or listened to music or news on the radio, or watched
anything on TV, then you've used radio waves for one-way communication.
Electricity isn't used for communication, but it's used to power all of those other devices.

What does a radio transmitter change electricity to?
A radio transmitter converts electrical energy into electromagnetic waves. This process involves modulating the electrical signals, which encode information, onto a carrier wave that can travel through the air. The result is radio waves that can be transmitted over distances to communicate signals like music, voice, or data to receivers.
How do long wavelength radio waves communicate over big distances?
aids
Do satellites normally use microwaves or radio waves?
Microwaves are radio waves.Most satellites communicate in microwave radio frequency bands.
Can people disrupt radio waves by standing in front of them?
Yes. Radio waves are electromagnetic and are affected by anything that conducts electricity. The human body is mostly made of water, which conducts electricity and therefore affects radio waves. To demonstrate the effect, see what happens when you move around a radio tuned to a station with relatively poor reception.
When was radio waves first discovered?
In 1820 Hans Christian Oersted noticed that electricity could cause magnets to move. This was the first "discovery" of radio waves.
What do the telegraph and telephone have in common?
Both use electricity and radio waves to communicate.

Which will have the longest wavelengths light waves X-rays or radio waves?
Of the items on that list, radio has the longest wavelength and x-rays have the shortest.

Why is radio used on moon to communicate?
There is no air and sound waves do not propagate through vacuum.
