How is the signal received by a radio transmitted ?

 In radio communication, an antenna sends out a radio frequency (RF) signal, which is picked up by another radio.

The radio frequency (RF) signal can be transmitted in two different ways: by electromagnetic waves in space (also known as "skywaves") or through the ground (also known as "ground waves").

When compared to ground-based transmissions, radio frequency (RF) signals carried via space (also known as "sky waves") tend to be more powerful. 

Radio waves are picked up by an antenna and transmitted to a receiver, where they are transformed into an electrical signal and ultimately audible sound.

The electromagnetic waves emitted by a radio transmitter have frequencies between about 100 kilohertz and 10 gigahertz.

The radio waves are broadcast in every direction, and they will only stop when they either collide with something or are deflected by a barrier. 

That which bends or disperses around a barrier is known as

The signal travels to a receiver, which then reconstructs the data as an auditory or visual signal.

The two types of radio communication are the send type and the receive type. A transmitter is the device responsible for sending out signals to a receiver.

Typically, the receiver is an antenna, but it could also be a human using a wireless headset or earpiece. By means of electromagnetic induction, radio waves travel over a frequency range from around 3 kilohertz to about 300 gigahertz.
