Radio waves were discovered before the radio was invented.
might be in Germany or russia or America
In 1820 Hans Christian Oersted noticed that electricity could cause magnets to move. This was the first "discovery" of radio waves.
Radio waves were first predicted by mathematical work done in 1865 by James Clerk Maxwell. Maxwell noticed wavelike properties of light and similarities in electrical and magnetic observations. He then proposed equations that described light waves and radio waves as waves of electromagnetism that travel in space. In 1887, Heinrich Hertz demonstrated the reality of Maxwell's electromagnetic waves by experimentally generating radio waves in his laboratory.
no, mechanical waves are not radio waves
The pulsing radio waves from the discovered object were detected using radio telescopes that can pick up and analyze radio signals emitted by celestial objects in space.

Radio waves travel at 186,000 miles per secondThey were discovered in 1865 by James Clerk Maxwell
No. Radio waves were discovered around 1880. The first radio stations began about 1920..
Aside from radio transmiters set up by humans. nearly every thing emenates high frequency radio waves.

the radio waves be improved by using the bigger signals
Electromagnetic wave were discovered not invented.
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
We are using radio waves to send messages to outer space.
