Radio waves= RS

Used to transmit all types of information. It started 100 years ago, by broadcast caring, and morse code followed by audio, one of the latest innovations was Television Broadcast.

-Radio waves to transmit and receive information.
-Radio frecuency signals are made above electric and magnetic waves, they are referred to as "electromagnetic waves" ( two waves, very in intensity, overtime forming two separate but related waves, perpendicular angles to each other).

-Horizontally= Magnetic wave.

-Vertically= Electric wave. 

They can be viceversa, polarized the polarity.

The RF Signal could be horizontal, vertical, circular.. 

-ElectroMagnetic Radiation is not radioactive.

-How quickly the electric and magnetic fields very in intensity or isolate determines their frequency travel speed of light. 

1 Cicly determines the wavelenght.

-Lower frequency = Longer wavelenght.

-Higher frequency = Shorter wavelenght.

Speed of light/ frequency = wavelenght ( lambda) 

Antennas: Based on their structure, the waves got the high. The element must match, the physical shape and size components depende of this cause affect the signal. 

The tall of antennas are bigger than the wave, normally it's use a 1/4 of the original wave.
