What is a wireless transmission medium that distributes radio signals through the air over long distances?
Broadcast Radio
What uses radio waves to transmit data signals over short distances and does not need a direct line of sight?
WiFi modems, highway toll transponders, and Bluetooth® thingies do that.

broadcast
Why were long-range radio signals important?
so people could communicate over long distances
Why do they use the radio to communicate?
-- It's easy and cheap to generate radio signals and put information on them. -- It's easy and cheap to detect radio signals at a great distance and recover the information from them. -- It's easy and cheap to pick out the radio signal you want from thousands of other signals. -- Radio can deliver information over great distances significantly faster than carrier pigeons, surface mail, runners, smoke signals, jungle drums, or optical fiber can.
What does AM and FM on the radio stand for?
Amplitude Modulation and Frequency Modulation. They are different methods of transmitting radio signals. AM is good for transmitting radio signals long distance FM is good for transmitting radio signals short distances but better quality

What waves that have the longest wavelength and are used to carry audio and picture signals over long distances are known as?
They are called as radio waves. They have got the speed of light. The wave length of the radio wave may be up to few kilometers.
How do radio antennas work to receive and transmit signals?
Radio antennas work by converting electrical signals into electromagnetic waves that can travel through the air. When a radio station transmits a signal, the antenna sends out electromagnetic waves. When a radio receiver picks up these waves, the antenna converts them back into electrical signals that can be processed and heard as sound. This process allows for the transmission and reception of radio signals over long distances.

Why was the three-electrode vacuum tube important?
It made it possible to amplify weak radio signals and transmit them over long distances

In which date the first radio was invented?
The first radio was invented by gugliemo marconi but jc Bose who first showed that radio signals could be sent over long distances without wires. Radio was invented in i921.Ansered byvaibhav gupta
