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).

What can radio telescopes do that optical telescopes cant?
No. The gain of the antenna ... which translates directly into angular resolution ... depends on the wavelength (frequency) of operation.The 2.5 meter optical parabolic reflector (telescope) on Mt. Wilson is a titan. 2.5 meter parabolic radio antennas are routinely used in intercity microwave communication but would be quite useless for serious radio-astronomy, as they are such shrimps at radio wavelengths.
What type of radio sounds do radio telescopes hear?
Stars broadcast from x-rays down through infrared, and radio telescopes take advantage of this by tuning in to the emissions, dubbed "radio" to differentiate from "optical" here, not because the star is necessarily being monitored in our "radio" spectrum.
The resolution of radio telescopes has been improved by what spectrographs charge-coupled devices photometers or interferometers?
interferometers because charge-coupled devices are only used in optical telescopes
Why can radio telescopes be used 24 hours a day?
Unlike visible light waves, radio waves can penetrate through clouds.
What instrument was most helpful in the advancement of astronomy?
Historically, it was the optical telescope. Modern radio telescopes, and cameras mounted on satellites, have advanced astronomy even further.
How do radio telescope operate?
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).
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Are optical telescopes much bigger then radio telescopes?
No they are not bigger then radio telescopes at all.
How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Do Optical telescopes have poorer resolution than radio telescopes?
Not necessarily.
How do optical telescopes and radio telescopes gather info about stars?
using radio waves it collects the data.
How are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
Are radio telescopes detect objects that optical telescopes cannot?
Yes, that is correct.
Do Radio telescopes have poorer angular resolution than optical telescopes because radio waves have a much longer wavelength than optical waves?
yes
In what ways are radio telescopes better than optical telescopes?
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.
How are space telescopes controlled?
Radio signals are sent from Earth, to operate the telescopes.
What other kinds of radiation are detected by telescopes?
Researchers use all of these: -- optical telescopes -- radio telescopes -- x-ray telescopes -- infra-red telescopes -- ultraviolet telescopes
