How much better is a 10-meter diameter mirror than a 5-meter diameter mirror, in a space telescope for visible/optical light? 4 times more collecting area, 2 times better angular resolution.

## How does the light collecting area of a telescope with a 10 meter diameter mirror compare to that of a telescope with a 5 meter diameter mirror?

Answer: The 10 meter telescope has 4 times as much light collecting area as the 5 meter telescope.

## How does the light collecting area of an 10 meter telescope compare to that of a 2 meter telescope?

2. Angular resolution: Telescopes that are larger are capable of taking images with greater detail. How does the collecting area of a 10-meter telescope compare with that of a 2-meter telescope? a) It’s 5 times greater.

## What is the collecting area of a 10 m diameter telescope?

Collect more light: in order to detect fainter objects. This is the most important function of telescopes. Thus, a 10-in diameter telescope collects (10/5)^{2} = 2^{2} = 4 times as much light as a 5-in telescope. An 8-in telescope (widely used by amateur astronomers) collects 1600x more light than the human eye.

## How does the light collecting area of an 8 meter telescope compare to that of a 1 meter telescope?

How does the light-collecting area of an 8-meter telescope compare to that of a 2-meter telescope? The 8-meter telescope has 16 times the light-collecting area of the 2-meter telescope.

## How does the light collecting area of a telescope with a 10-meter diameter mirror compare to that of a telescope with a 5 meter diameter mirror quizlet?

How much better is a 10-meter diameter mirror than a 5-meter diameter mirror, in a space telescope for visible/optical light? 4 times more collecting area, 2 times better angular resolution. You just studied 33 terms!

## How do you calculate the light collecting area of a telescope?

Since most telescope objectives are circular, the area = p × (diameter of objective)^{2}/4, where the value of p is approximately 3.1416. For example: a 40-centimeter mirror has four times the light-gathering power as a 20-centimeter mirror [( p40^{2}/4) / ( p20^{2}/4) = (40/20)^{2} = 4].

## How will the light collecting area of the Thirty meter telescope compare to one of the Keck telescopes?

The light collecting capability of the TMT will be 10 times that of the Keck Telescope, and more than 144 times that of the Hubble Space Telescope.

## How does the light collecting area of a 4 meter telescope compared to that of a 1 meter telescope?

A telescope’s diameter tells us its light-collecting area (like wider buckets collect more rain). … So a 4-meter telescope has 16x the light collecting area of a 1-meter telescope.

## What is the light collecting area of a 3m diameter telescope?

The amount of light that a telescope can collect is proportional to the cross-sectional area. Now the area of a circle is A=PiR^2=Pi(D/2)^2 in terms of the diameter. Since the area is proportional to the square of the diameter, a 3m diameter telescope can collect 3^2=9 times as much light as a 1m diameter telescope.

## How does the light gathering power of a telescope depend on its diameter?

The light-gathering power of a telescope is directly proportional to the area of the objective lens. The larger the lens, the more light the telescope can gather. Doubling the diameter of the lens increases the light gathering power by a factor of 4.

## What part of a telescope is responsible for gathering in light and making objects appear brighter?

A telescope’s ability to collect light is directly related to the diameter of the lens or mirror — the aperture — that is used to gather light. Generally, the larger the aperture, the more light the telescope collects and brings to focus, and the brighter the final image.

## How much more light is collected by a telescope with a mirror that is 30 meters in diameter compared to a telescope with a 10 meter mirror?

TMT, with its 30-meter (nearly 100-foot) diameter mirror, will have nine times the light-gathering power of today’s best telescopes. When compared to the Hubble Space Telescope, TMT will have 156 times the collecting area and more than 10 times its resolution at certain wavelengths.

## How does the light collecting area of an 8 meter telescope compare to that of a 2 meter telescope group of answer choices?

The 8 meter telescope has 16 times the light collecting area of the 2 meter telescope.

## What does NASA’s Sofia stand for?

SOFIA, the Stratospheric Observatory for Infrared Astronomy, is a Boeing 747SP aircraft modified to carry a 2.7-meter (106-inch) reflecting telescope (with an effective diameter of 2.5 meters or 100 inches).

## How much more light does an 8 meter telescope gather than a 2 meter telescope?

A) The 8-meter telescope has 16 times the light-collecting area of the 2-meter telescope.
