That's a 'radio telescope'.
Radio telescopes detect radio waves.
Dr. Heinrich Hertz
sattelites
In a vacuum radio waves travel at the speed of light, about 186,000 miles per second.
Gamma rays
No. He was content to be able to generate radio waves and then detect them all the way across the room.

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.
Radio waves from your calling device gets sent to the satellite in space then carried to the other device
its collects data from space. It is a device that converts electrical energy into Radio waves or TV waves sending them out or receiving them.
A radio altimeter bounces radio waves off the ground to detect elevation.
Different devices are used to detect different frequency ranges of electromagnetic waves. You simply can't use the same device to detect x-rays, than you would use to detect radio waves, for example.
mainly electromagnetic radiation, heat and light, but with a dash of radio waves and particles as well.Gravity waves should exist as well, but we yet have the apparatus to reliably detect them.
a device that converts radio waves to audio waves
