# Best answer: How many times larger is the collecting area of a 4 meter telescope than a 1 meter telescope?

Contents

Therefore, with 16 times the area, a 4-m telescope collects 16 times the light of a 1-m telescope.

## How much greater is the light collecting area of a 4 meter telescope than a 1 meter telescope?

A telescope’s diameter tells us its light-collecting area (like wider buckets collect more rain). If the telescope has a diameter of d, it has a collecting area: So a 4-meter telescope has 16x the light collecting area of a 1-meter telescope. The largest telescopes currently in use have a diameter of about 10 meters.

## How much greater is the light collecting area of a 3 meter telescope than a 1 meter telescope?

How much better is the resolution? The light-collecting area would be 4x greater on a 6-meter (which has 36) telescope than a 3-meter telescope (which has 9).

## How much more light will a 4 meter telescope collect than a 2-meter telescope?

So, given two telescopes of different apertures (say one that is 1 meter across, and the second that is 4 meters across), the light gathering power of the 4 meter telescope is (π)(22) / (π)(0.52) = 16 times better.

## How much more light does a 3 m diameter telescope collect than a 1’m diameter telescope?

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 much more light will a 10 meter telescope collect than a 5 meter telescope?

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

## What is the light collecting area of a telescope?

The aperture of a telescope is the diameter of the light collecting region, assuming that the light collecting region has a circular geometry . For an optical instrument, the aperture is the diameter of the objective lens (refracting telescope) or the primary mirror (reflecting telescope).

## 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 a 2-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 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 many times more light can be collected by a telescope with a mirror that is 4 times larger than another telescope?

The amount of light a telescope can collect increases with the size of the aperture. A telescope with a mirror that is 4 meters in diameter can collect 16 times as much light as a telescope that is 1 meter in diameter.

## How much more light would a 10 telescope collect compared to a 2 telescope?

Purposes. 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 = 22 = 4 times as much light as a 5-in telescope.

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

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

## What are 3 properties of optical telescopes?

Telescopes have three properties that aid astronomers: (1) light-gathering power, which is a function of the size of the objective—large objectives gather more light and therefore “see” farther into space; (2) resolving power, which allows for sharper images and finer details, is the ability of a telescope to separate …

## How do you find the 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 [( p402/4) / ( p202/4) = (40/20)2 = 4].

## What advantages does a large diameter astronomical telescope have over a telescope of a smaller diameter?

What advantages does a large diameter astronomical telescope have over a telescope of a smaller diameter? Larger diameter better light gathering capabilities and better resolving power.
