1) Any object that emits radiation (because of its temperature) will emit in all wavelengths, including visible light, infrared, radio waves, ultra-violet, etc.
What changes is the proportion of each (which depends directly on the temperature).
2) The Earth's atmosphere is transparent to radio waves (meaning: it is easy to receive radio waves from space -- in general they are not blocked by the atmosphere).
3) It is easy to build a receiver that gives us the direction from which the radio waves are coming. We can draw maps of radio sources (the same way that taking pictures in visible light lets us draw maps of the visible stars).

What is the radio interferometer?
A radio interferometer is a scientific instrument used to observe and study radio waves emitted by celestial objects such as stars, galaxies, and quasars. It consists of multiple radio antennas or dishes that are spread out over a large area and work together to create a combined signal. By combining the signals from different antennas, a radio interferometer can create high-resolution images and precise measurements of radio sources in the universe.
A device used to detect radio waves from objects in the space?
A radio telescope
How can radio waves can affect the tsunami and earthquakes?
They can't. Radio waves are used to transmit information about earthquakes and tsunamis, but cannot affect the events themselves.
What is frequency of a satellite wave?
I never heard of a "satellite wave". If you mean the radio waves used by satellites for communication - well, like all radio waves used for such purposes, there is probably a large range of waves they can use.
How many parts of electromagnetic spectrum are used for communications?
Every part of the electro-magnetic spectrum could be used for communications however the most exploited are long radio waves, short radio wave, and micro-waves.
Are radio waves able to reach the earth?
Yes. This is used all the time by ground-based radio telescopes, which observe outer space.
What instrument was used during the Age of Exploration to observe stars?
At the Age of Exploration they used telescope to observe stars.
What waves that are used in radar?
Electromagnetic waves.
What are the wave qualities used by radio broadcasters to code radio waves?
All of them can be used to add information to the waves.
Radio waves and useful of radio?
how are radio waves be used- well they are used by sound waves like as in u can hear sond waves but radio waves is where you are in the car and u are listening for instance capital fm that is radio waves Hope It Helped Hennddyyyy:) :D
How is radio waves used in everyday life?
to send radio waves through the air to make the radio work
Why are satellite used to relay radio waves?
Satellites are used to relay radio waves to the other side of the world because radio waves cannot travel directly through the Earth.
Are telescopes only used at night?
No. They are generally used to look at stars at night, because that's when it's easiest to see them. But some telescopes are used at sea and there's also a type of telescope called a radio-telescope that searches the stars for radio waves during daylight hours.
Waves used for broadcastig radio signals are called what?
The waves used to broadcast radio signals are called RF waves and these generally lie in VHF and UHF band of electromagnetic spectrum.
What is waves used for?
radio waves are used in tv communication, weather broadcasting

Which electromagnetic waves are used for communication in space?
radio waves
