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).

Astronomers use instruments to observe the universe What instruments is used to observe distant stars?
Astronomers primarily use telescopes to observe distant stars. These can be optical telescopes, which capture visible light, or radio telescopes that detect radio waves emitted by celestial objects. Additionally, space-based observatories like the Hubble Space Telescope provide clearer views by avoiding Earth's atmosphere, while instruments like spectrometers analyze the light from stars to determine their composition, temperature, and motion.
What are other kinds of telescope used by astronomers to observe star?
Some other types of telescopes used by astronomers to observe stars include radio telescopes, which detect radio waves emitted by stars, and space telescopes like the Hubble Space Telescope, which is specifically designed for observations in space without the distortion caused by Earth's atmosphere. Astronomers also use infrared telescopes to study stars emitting infrared radiation, providing valuable insights into their composition and temperature.
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.
How are radio telescopes different from the keck tetescopes?
Radio telescopes and Keck telescopes differ primarily in the type of electromagnetic radiation they observe. Radio telescopes detect radio waves emitted by celestial objects, allowing astronomers to study phenomena like pulsars and cosmic microwave background radiation. In contrast, the Keck telescopes, which are optical/infrared telescopes located in Hawaii, observe visible and infrared light, enabling detailed imaging and spectroscopy of stars, galaxies, and other astronomical features. This distinction in wavelength leads to different techniques and instruments used in their respective observations.
When did Grote Weber invent the radio telescope?
Grote Reber, not Grote Weber, is credited with building the first radio telescope in 1937. He used a parabolic antenna to observe radio waves from outer space, laying the foundation for modern radio astronomy.
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 are other kinds of telescope used by astronomers to observe star?
Some other types of telescopes used by astronomers to observe stars include radio telescopes, which detect radio waves emitted by stars, and space telescopes like the Hubble Space Telescope, which is specifically designed for observations in space without the distortion caused by Earth's atmosphere. Astronomers also use infrared telescopes to study stars emitting infrared radiation, providing valuable insights into their composition and temperature.
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
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.
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.
What are Electromagnetic waves used in broadcasting are called?
Electromagnetic waves used in broadcasting are called radio waves. They are used to transmit signals for radio, television, and communication systems.

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
