An optical telescope is designed to gather and focus light energy; a radio telescope is designed to gather and focus other "flavors" of electromagnetic energy. We can see light with our eyes, but the Sun and all the stars emit electromagnetic radiation (which is what light is) at ALL frequencies.
It wasn't until the late 1800s that radio receivers were invented. We became aware of sources of radio waves in the sky when Karl Jansky discovered the phenomenon by chance in the 1931.
Radio telescopes were developed shortly after World War 2.
Astronomy was first discovered in the times of ancient Greece

Radio telescopes are mainly used for astronomy.
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.
