What instrument to astronomers use?
They use telescopes, but different types of telescopes. There are telescopes for radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays, all depending on what it is you're trying to see.
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.
Why do you use only two types of telescopes here on earth optical or radio telescopes?
Radiation other than light and radio waves hardly penetrates Earth's atmosphere.
What telescope does not use visual light energy?
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
Why can radio telescopes withstand weather conditions and optical can not?
Optical telescopes rely on light waves being sent from the object being observed. Weather conditions (clouds) can block the light from the object reaching the telescope's lens. Radio telescopes only search for radio-waves being sent from the object under scrutiny - which are not (as a rule) affected by weather conditions on earth.
How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
How radio telescopes differ from optical telescopes.?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
What is the difference between light radio and infrared telescopes?
your mu said its different so it is
What type of telescope does not use optics?
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.
What are types of telescopes?
Light telescopes which are refractor and reflector and radio ones.
What type of telescopes?

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 are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
Why are radio telescopes not located on top of mountains like the visible light telescopes?
It is not necessary to do so, as atmosphere doesn't distort radio signals as much as visible light.
How is an optical telescope different from the others?
An optical telescope focuses and concentrates visible light; radio telescopes focus and concentrate electromagnetic radiation (which means, "light") in the radio part of the spectrum.
How are the Keck telescopes different from radio telescopes?
keck telescopes 1,2 tie the records for the largest telscopes in the world
