What is Radio Waves

"Radio waves" transmit music, conversations, pictures and data invisibly through the air, often over millions of miles -- it happens every day in thousands of different ways! Even though radio waves are invisible and completely undetectable to humans, they have totally changed society. Whether we are talking about a cell phone, a baby monitor, a cordless phone or any one of the thousands of other wireless technologies, all of them use radio waves to communicate.








Here are just a few of the everyday technologies that depend on radio waves:

AM and FM radio broadcasts
Cordless phones
Garage door openers
Wireless networks
Radio-controlled toys
Television broadcasts
Cell phones
GPS receivers
Ham radios
Satellite communications
Police radios
Wireless clocks  


Ha ha The list goes on and on... Even things like radar and microwave ovens depend on radio waves. Things like communication and navigation satellites would be impossible without radio waves, as would modern aviation -- an aircraft depends on a dozen different radio systems( like radar,positioning system GPS,navigation,signal receivers,etc).
The new era INTERNET ,wireless access is because of radio,which sends and receives datas to one place to other via transmitter and receivers.
