Keck telescopes do not exist, Keck telescope refers to the WM Keck Observatory on Mt. Kea.
The Keck Observatory is comprised of several opticalreflecting telescopes, whereas a
radio telescope consists of a large parabolic solid metal or screen reflector with a radio
receiver at its focus, built to detect and measure radio 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).
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.
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.
Radio telescopes allow us to see things that can't be seen in visible light. And vice versa, optical telescopes can show things that are not visible in radio telescopes. So, the information from both kinds of telescopes really complements each other.
interferometers because charge-coupled devices are only used in optical telescopes
They are optical telescopes.

I have no idea and it does not even say it in the textbook
The Keck telescope has a 10m mirror.
10 m
The telescopes' primary mirrors are 10 meters in diameter.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.

No they are not bigger then radio telescopes at all.
Telescopes can be made to see in almost any part of the electromagnetic spectrum: visible light, infrared light, ultraviolet light, X-rays, or radio waves. The largest telescopes are those for radio waves - in Arecibo there is one with a diameter of 300 meters. I am not sure whether it is the largest, though.
your mu said its different so it is
