Placing the telescopes in valleys is believed by some people to slightly reduce radio interference, but when radio telescopes are placed in valleys, it is usually because they are so large and the mountains work as supports, to reduce the cost.
I'm assuming it is because of less city light inference.
No.
Radio telescopes are basically specially designed antennas. They don't "see" anything. They "hear".
no, reflecting telescopes.
Not necessarily.
Yes, that is correct.
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
No.
Radio telescopes collect radio waves. Optical telescopes capture visible light waves.
No they are not bigger then radio telescopes at all.
A radio telescope is a form of directional radio antenna used in radio astronomy. The same types of antennas are also used in tracking and collecting data from satellites and space probes. In their astronomical role they differ from optical telescopes in that they operate in the radio frequency portion of the electromagnetic spectrum where they can detect and collect data on radio sources. Radio telescopes are typically large parabolic ("dish") antennas used singly or in an array. Radio observatories are preferentially located far from major centers of population to avoid electromagnetic interference (EMI) from radio, TV, radar, and other EMI emitting devices. This is similar to the locating of optical telescopes to avoid light pollution, with the difference being that radio observatories are often placed in valleys to further shield them from EMI as opposed to clear air mountain tops for optical observatories.
Radio telescopes. I believe the largest INDIVIDUAL radio telescope has a diameter of about 300 meters. Moreover, several of those are often connected to work in unison.
Radio telescopes gather data from radio sources and they target the radio frequency part of the electromagnetic spectrum.

Valleys Radio was created on 1996-11-23.
That refers to researching the Universe by observing radio waves. Special telescopes - radiotelescopes - are built for this purpose; they are often quite large.
no, reflecting telescopes.
using radio waves it collects the data.
