Question

What are radio telescopes? Explain the working of radio telescopes.

Answer 1

A special type of telescope used to produce images of the sky objects by processing the radio ways emitted by them is called radio telescope.
It is made from one or more dishes of a particular parabolic shape. As in optical telescope the incident radio waves are reflected by these dishes and converge at the focus. A radio receiver is placed at the focal point. The information gathered by this receiver is passed on to a computer which analyses it and constructs an image of the source.
