It was Warren G. Harding, in 1921. Not a lot of people heard him (most people did not begin to get radios till 1922), but it was written up in the newspapers. By all accounts, Harding was a big fan of radio, which was a new mass medium when he was president. He was also the first president to install a radio in the White House, in early February 1922.

When was radio waves first discovered?
In 1820 Hans Christian Oersted noticed that electricity could cause magnets to move. This was the first "discovery" of radio waves.
Does mechinal waves have radio waves?
no, mechanical waves are not radio waves
How are electromagnetic waves different to radio waves?
Radio waves ARE electromagnetic waves.
Who detect radio waves first?
Dr. Heinrich Hertz
How was the radio waves discovered?
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.

Are radar waves visible?
No. Radar waves are one category of radio waves. Think of all the radio waves that are all around you right now . . . AM radio, FM radio, police and fire radio, highway patrol radio, taxi radio, television picture and sound radio waves, cellphone radio waves, garage-door-opener radio waves, bluetooth radio waves, WiFi waves, microwaves ... and you can't see any of them ! Radar waves can easily be there in the group.
The first transmission of radio waves?
James Clerk Maxwell
Who detect radio waves first?
Dr. Heinrich Hertz
What were detected in space for the first time in 1938?
Radio waves were detected in space for the first time in 1938. At the time, radio waves traveled around 60 light years away.
How are radio and television waves added to em radio waves?
by changing the amplitude or frequency of the radio waves.
