No. He was content to be able to generate radio waves and then detect them all the way across the room.
In 1820 Hans Christian Oersted noticed that electricity could cause magnets to move. This was the first "discovery" of radio waves.
no, mechanical waves are not radio waves
Like bats do in caves it is a signal sent out and timed so the distance can be measured from the reflected sound waves or in this case radio waves that bounce off any objects or obstacles.
A radio altimeter bounces radio waves off the ground to detect elevation.
A radio telescope.

I do not believe that the Hubble is equipped for radio astronomy. Certainly it can "detect" radio waves; it is remote-controlled by radio. But most radio astronomy is done with earth-based dish antennas.

No, a radio cannot detect radioactivity. A radio is called a radio because of the radio waves that it operates on.
Yes.
Humans cannot detect electromagnetic waves outside of the visible light spectrum, such as ultraviolet light, infrared radiation, and radio waves. Additionally, humans cannot directly detect gamma rays and X-rays.
There are telescopes used to detect radio waves and others to detect infrared radiation.
