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).

Radio waves can be used to observe stars by detecting the radio signals emitted by celestial objects. These signals provide information about the composition, temperature, and movement of stars. Radio telescopes are designed to receive and amplify these signals, allowing astronomers to study stars and other astronomical phenomena through radio wave observations.

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.


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.


Is the radio telescope an instrument which measures radiation?

Yes, a radio telescope is an instrument specifically designed to detect and measure radio waves emitted by celestial objects in space. It is used to study and observe radio emissions from various astronomical sources, providing valuable information about the universe.


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.

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


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.
