Want this question answered?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
No they are not bigger then radio telescopes at all.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
Not necessarily.

using radio waves it collects the data.
They are optical telescopes.
Yes, that is correct.
yes
Both types of telescope collect and focus electromagnetic radiation for observational purposes, the difference is their band of observed frequencies. Radio telescopes are used for the radio frequencies ( ~3km - ~30cm) while optical telescopes are used for frequencies closer to visible light ( ~0.7μm - ~0.4μm). Optical telescopes may also be able to detect infrared and ultraviolet light.
The surface of a radio telescope doesn't have to be as flawless as the surface of an optical telescope because the radio telescope is collecting radio waves, something that will not be affected by faults in the glass. Optical telescopes, on the other hand, are collecting light, where faults in the surface can interfere with the image.
