Only those which aren't absorbed too much by the atmosphere. Those are visible light, and radio waves.

How do astronomers observe the sun at different wavelengths?
Cus they is BOSS
How would earth appear at radio wavelengths to extraterrestrial astronomers?
as a highly variable set of transmissions that would repeat roughly every 24 hours
What are two ways the atmosphere limits what astronomers can detect?
i think because of pollution and lots of light
Did astronomers believe that the sun was part of earth?
No.
Our eyes detect wavelengths as what?
The eyes of all seeing animals are restricted to a narrow range of the electromagnetic spectrum with wavelengths from about 400 to 700 nm (nanometers). Within this range, not all animals can distinguish between different colors; some see in shades of grey. A healthy human eye, which does distinguish between different colors, normally detects wavelengths from 390 nm (violet) to 750 nm (red). Some animals can detect wavelengths slightly into the ultraviolet region of the spectrum, i.e. wavelengths shorter than 390 nm, that humans cannot detect. Colors that are visible to humans run from violet through blue, cyan, green, yellow, orange, and finally red. Brown is a mix of red, yellow, and blue. White is a mix of all the colors at once. Black is not a color, but the lack of color because a black surface absorbs light without reflecting much of it back.

Which wave can your eye detect?
If you mean, "which wavelengths of light can the human eye detect," the human eye can see wavelengths from about 390 to 700 nanometers.
Why can wavelengths of light be seen by humans?
Our eyes can detect them.
Why does a rainbow show colors from reds to violet?
There's a broad band of wavelengths of light coming from a rainbow. They range from wavelengths that are too short for your eyes to detect, all the way to wavelengths that are too long for your eyes to detect. Within that band of wavelengths is the total band that your eyes can detect, and you see them as a spread out display of all the colors that your eyes and brain can work together to perceive.
Arab Astronomers determined that the earth was what?
Arab astronomers determined that the Earth is flat.
Indian astronomers recognized that earth?
India astronomers recognized that the earth was a sphere.
Why are there diiferent telescopes in space?
To detect different wavelengths of the electromagnetic spectrum.
What did ancient astronomers know about the earth?
Ancient Greeks such as Aristotle recognized that Earth and the Moon are spheres, and understood the phases of the Moon, but because of their inability to detect stellar parallax, they rejected the idea that Earth moves. Eratosthenes measured the size of Earth with surprising precision.
How do the wavelengths of electromagnetic energy absorbed by materials on Earth compare to the wavelengths radiated by materials on earth?
s
Which wavelength of radiation do astronomers use to detect these hottest stars in our galaxy?
infrared
What kind of spectrum do astronomers find most useful?
The continuous spectrum is extremely important to astronomers. Objects as well as gasses can be located by the direct wavelengths that are presented at any time.
