No. Radio telescopes are the largest, consisting of multiple (sometimes hundreds) of dishes tens of metres across in enormous arrays.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
No they are not bigger then radio telescopes at all.
The largest optical telescope in use today is the Gran Telescopio Canarias (GTC) located at the Roque de los Muchachos Observatory in La Palma, Canary Islands. It has a primary mirror diameter of 10.4 meters (34 feet). Another large optical telescope is the Keck Observatory in Hawaii with two telescopes, each with a primary mirror diameter of 10 meters (33 feet).
Not necessarily.
They are optical telescopes.
Yes, that is correct.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.

Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes
the optical telescope has discovered objects on earth and in space
