Questions 1 Describe how radio telescopes are used to explore space.

2. How are radio waves used on Earth?

3. Why do radio telescopes convert radio waves (analog signals) to electrical (digital) signals for analysis? (Hint: What did the article say about the advantages of digital signals?)​

1)A radio telescope is a form of radio receiver used in astronomy. In contrast to an "ordinary" telescope, which receives visible light, a radio telescope "sees" radio waves emitted by radio sources, typically by means of a large parabolic ("dish") antenna, or arrays of them.

2) Various frequencies of radio waves are used for television and FM and AM radio broadcasts, military communications, mobile phones, ham radio, wireless computer networks, and numerous other communications applications. Most radio waves pass freely through Earth's atmosphere.

3)Radio telescopes are devices used to capture radio light waves, bring it to focus, overdraw it and and use the data for processing and analysis. ... These radio light waves, that are raw analog signals are converted into digital signal so as to create and distinguish fine details in the universe.
