RADIO WAVS

.

Radio waves have the longest wavelength in the electromagntic spectrum. These waves can be longer then a football field or as small as a football. Radio waves do more than bring music to your radio. They also carry signalas for your TV and phones.

Radio waves are made by various typse of transmitters, depending on the wavelegth. Theyare also given off by stars, sparks, and lightning. That is why you hear interfeernces onyour radio in a thunderstorms.

Radio waves is one of the largest, independent, two-way radeo providers in the world

Radio waves are part of a larger group of waves classified all to sether a electromagnrticradiation. This large group of waves is broken down into smaller groups based upon theirfreqwencies and wavrelengths.

I proved the existence of radeo waves in the late 1880.

Heinrich Hertz

Radios transmit sine waves (smooth and repeitive oscillations) into space, but sinc waves can't carry info on their own. They need to be modulated in same way, so that info say, on the voices on your favorite radio stations can be ehcod on the waves. That's where the ''M'' cames from in AM na FM radio:modulation. There are 3 types of modulations*Pulse Modulation(PM)*Ampliude Modulation(AM)*Frequeney Modulation(FM)
