Question

Explain the construction of a radio telescope. 

Answer 1

The radio telescopes are used to see radio waves coming from space. It has one or more dishes of parabolic shape. The rays coming from the distant source are first reflected by these dishes, which converge at the focus. A radio receiver is placed at the focal point, which gathers the information. The gathered information is then passed on to a computer, which analyses it and constructs an image of the source.
