How much greater would the light collecting area of a 60-meter telescope be than that of the 10-meter Keck telescope?
Mkinsie444
The ratio of the area is (60 / 10) squared, or 36.

What is meant by collecting area. How does it affect the ability to see faint objects?
Collecting area is the area over which a telescope focuses and collects light from a particular object. Generally this is the size of the opening of the telescope. The greater the collecting area, the more photons per second the telescope can collect from the area of interest. Having more collecting area reduces the amount of time for any exposure to be made. For really faint objects having more collecting area can bring the object above the observing threshold of the equipment you have, making it possible to detect it.
How does the telescope help in the study of the heavenly bodies?
The telescope magnifies the image of an object, allowing us to see it in greater detail.

How much greater is the light-collecting area of one of the 10-meter Keck telescopes than that of the 5-meter Hale telescope?
A 1 m telescope has a collecting area of pi x 1 x 1 = 1 piA 3 m telescope has a collecting area of pi x 3 x 3 = 9 pi.Therefore, the bigger telescope collects 9 times as much light.
Why some star that are invisible to the unaided can be seen with a telescope?
Because the main function of a telescope is to make things brighter. It does thatby collecting the light from an object over a much greater area than the lens ofyour eye does.-- The lens of your eye is maybe 1/2 inch in diameter.-- The lens of the largest refracting telescope is 40 inches in diameter, so it can collect6,400 times as much light from a star as your eye can.-- The mirror of the largest reflecting telescope is 400 inches in diameter, so it can collect640,000 times as much light from a star as your eye can.
If the radius of an objective mirror of a telescope is tripled its light-gathering power is likely to become?
9 times greater.
What tools help modern people study objects in space in greater details than was possible in the past?
The Hubble telescope helps modern people study objects in space in greater detail.
Why does the HST get better pictures than a telescope earth?
The Hubble Space Telescope doesn't get affected by the Earth's Atmosphere. It also has the advantage of being in space so the quality and variety of images are a lot greater then any optical telescopes on Earth.
What is super sonic?
In general, it is speed greater than the speed of sound. It is also a super transformation of Sonic the Hedgehog after collecting all of the chaos emeralds.
For a research telescope (with a long focal length) would the thickness be greater or less than for a backyard telescope (with a short focal length)?
Technically the shorter the focal length, the thicker the mirror. But some short focal length telescopes have relatively thin mirrors all the same.
Why are most large telescope reflecting telescopes?
It is cheaper and easier to create mirrors rather than lenses. Large lenses become difficult to support the larger they become. Additionally, mirrored telescopes fold light waves so that a telescope can be shorter, the same size telescopes with lenses are greater in length.
How do Crime Scene Investigators benefit society?
By collecting, processing, and identifying evidence that can be used in identifying the perpetrators of offenses which aid in successfully removing the criminal element from the greater society
