well,both telescopes let you look into the ground into the inner core and you see deep in he atmosphere which is space.
Errr...
The Very Large Array is an array of radio-telescopes, i.e. it detects radio emissions from stars and similar.
An optical telescope as its name suggests, collects visible light.
The similarity is that increasing the aperture increases the radiation-gathering power by a square-law.
In an optical telescope this is achieved by a larger mirror (or lens but most large telescopes are reflecting.)
The VLA uses a "synthetic aperture" to gain the advantages of increasing its gathering area without the cost and complexity of building a single, very large dish.

Why doesnt the surface of a radio telescope have to be as flawless as the surface of a mirror in an optical telescope?
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.
Sample of optical instrument?
Example of an optical instrument? (not sample) Microscope.
Is the image produced by a radio telescope the same as the image produced by a optical telescope?
no you cant see image its appers in waves
How are the telescopes Keck I and Keck II different from radio telescope?
They are optical telescopes.
What rason could you give for placing an opical telescope into orbit instead of a radio telescope?
I can think of two big reasons right off the top of the bat:1). Radio signals are influenced by a trip through the atmosphere much less thanoptical ones are, so the downside of observing them from the surface is far less.2). Radio telescopes operate at wavelengths that are perhaps 15,000 times thewavelengths at which optical instruments do. So for comparable sensitivity andresolution, a radio telescope has to be 15,000 times the size of an optical one.Armed with this fact, your average Congressperson is not likely to support theprogram to fund a proposed Jansky Space Radio Telescope.
What telescope detects radio waves?
Arecibo, VLA
Is theHubble telescope is an optical telescope?
The Hubble Space Telescope has a number of instruments, but the primary one is an optical telescope.
What does a microwave telescope allow you to see?
this works someway but i dont kno so ask NASA. peace.
Why are reflecting telescope and refracting telescope considered as optical telescope?
"Optical", in this case, simply means that they work with light.
Which is the best telescope?
optical
What kind of telescope are most of the large optical telescope?
Reflector.
What is the advantage of using a non-Optical telescope over an optical telescope?
See things that don't shine in the visible spectrum.
Who invented the optical light telescope?
me
How do radio telescope different from optical telescope?
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
Where can you get the optical components to repair an old telescope?
you can get the optical components to repair an old telescope at http://www.astromart.com/classifieds/details.asp?classified_id=644695. Another site is www.Fixya.com/Telescope+Repair

What does the simplest optical telescope contain?
It contains an objective lens and a lens in the eyepiece of the telescope.
