Why is man made interference is the chief problem of radio telescopes?

Because all man's electrical and electronic equipment generates noise in the radio spectrum which masks weak electrical signals in a radio telescope.
The main problems are switch-mode power supplies as used in computers, TV sets, and data streaming down old-fashioned telephone lines. There are regulations that limit the amount of noise that is allowed from electrical and electronic equpiment but these are widely ignored.

Radio telescopes are often connected together to do interferometry What is the primary problem overcome by radio interferometry?
No.
Why are radio telescopes often placed in valleys?
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.
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 telescopes gathering data?
Radio telescopes gather data from radio sources and they target the radio frequency part of the electromagnetic spectrum.
What kind of telescopes do radio telescopes use?
Radio telescopes are basically specially designed antennas. They don't "see" anything. They "hear".
Is the design of radio telescopes very similar to the design of refracting telescopes?
no, reflecting telescopes.
How do optical telescopes and radio telescopes gather info about stars?
using radio waves it collects the data.
What are radio waves detected by?
Radio Telescopes and radio wires
Why do radio telescopes work better down in the valleys?
Radio telescopes tucked into valleys can "hide" in there from interference that may be radiated into the side of the antenna array from earth sources. Better shielding equals less noise (interference) and greater resolution of a desired signal. Remember that radio telescopes are highly directional, and they don't "see" signals to the sides well. Now consider the "closeness" of a source on earth compared to any space object that is an image objective. There is no comparison. Any source of interference on earth will be a zillion times "closer" and the signal will be a zillion times "larger" than a space objective, even though the noise is "coming in from the side" to hit the dish. Bad news for the radio astronomer. Hide the dish, slash interference radiated into the sides of your dish and get good (better) results. Piece of cake.

What are types of telescopes?
Light telescopes which are refractor and reflector and radio ones.
