Which Of The Following Is Not Important To Astronimers Placing A New Research Telescope? (Correct answer)

What is it about space that has scientists going to it for telescopes?

  • However, scientists and engineers are rapidly shifting their attention to space as the next frontier for sophisticated telescopes. It was in the 1960’s that astronomers began attaching large balloons to telescopes as a method of elevating them beyond the Earth’s lower atmosphere, kicking off the current trend toward space telescopes. Their purpose is to have a better perspective.

What is the most important property of a telescope for astronomers?

The ability of a telescope to gather light is the most significant characteristic. Increase the size of the aperture (the opening at the top of the telescope tube) and you’ll get more light collected by the telescope.

What are 2 ways that telescopes are useful to astronomers?

When it comes to telescopes, the most significant roles are (1) to gather dim light from an astronomical source and (2) to concentrate all of that light into a point or picture. The majority of astronomical objects of interest are exceedingly dim; the more light we can capture, the better we will be able to analyze these things.

Which of the following is the most important reason for putting telescope in space?

It is primarily for this reason why we send telescopes into space: to get around the Earth’s atmosphere and so acquire a sharper picture of the planets, stars, and galaxies that we are investigating. Our atmosphere works as a protective blanket, allowing only some wavelengths of light to get through while blocking others.

What makes the telescope such an important tool for astronomical research?

In astronomy, the telescope is without a doubt the most essential investigative instrument available. It provides a technique of collecting and studying radiation emitted by celestial objects, even those located in the furthest reaches of the cosmos.

What of the following properties of a telescope is least important?

The most significant feature of a telescope is its ability to magnify objects. Amateur and professional astronomers are well aware that the light-gathering and resolving powers of their telescopes are the most significant characteristics. Because these two skills are highly dependent on the objective, they ensure that the objective’s optics are of the highest quality.

What is the most important property of a telescope quizlet?

The light-collecting area and angular resolution of a telescope are the two most essential characteristics of a telescope. The light-collecting area of a telescope informs us how much total light it can capture at a given point in time.

What are the disadvantages of telescope?

Disadvantages:

  • In comparison to a reflector, the initial cost is quite significant. It is unavoidable to have some secondary spectrum (chromatic aberration) in the image (reflector completely free of this) The colors are unable to concentrate on a single location. Long focal ratios might indicate that the instrument is heavy and difficult to use.

Is the atmosphere good or bad for astronomers trying to use telescopes?

Even in our windy, weather-ravaged environment, there are nearly always minor temperature fluctuations present, and when you look through a telescope, you can see the amplified effect of these fluctuations. The majority of the “atmospheric sight” problem, on the other hand, occurs unexpectedly near to the telescope, where you may take efforts to mitigate it.

How do astronomers use the electromagnetic spectrum?

When studying objects in space, astronomers employ a variety of telescopes that are sensitive to different sections of the electromagnetic spectrum. Despite the fact that all light is basically the same thing, the method in which astronomers see light varies depending on the region of the spectrum they are interested in exploring.

What is the most important reason for putting an optical telescope in space quizlet?

Radio waves, visible light, and a few wavelengths of infrared light are the only wavelengths that can be detected from the ground. Consequently, the most significant purpose for launching telescopes into space is to enable us to see the rest of the electromagnetic spectrum.

What are the two main reasons why astronomers continually build telescopes with larger and larger diameters?

Why? Because in order to capture more light, we must construct larger-sized mirrors. Then and only then can we make out dim things. In order to observe more dim objects and to look further into the universe, huge telescopes are being built.

Which of the following is one important reason why most large astronomical telescopes are reflecting telescopes rather than refracting telescopes?

Reflecting telescopes are preferred by astronomers over lenses because bigger mirrors are lighter and easier to manufacture than large lenses, and they also suffer from less optical faults than lenses. Instruments can be placed within telescopes at the prime focus, or a secondary mirror can be employed to reflect the light to an external detector, depending on the situation.

What is an astronomical telescope?

astronomical telescope definition: a telescope that is built for seeing celestial bodies and does not require the use of an image-rectification device — as opposed to the terrestrial telescope.

What tools do astronomers use to study space?

astronomical telescope definition: a telescope that is built for watching celestial bodies and does not require an image-rectification system — this is in contrast to a terrestrial telescope, which must.

  • Telescopes with optical elements. The optical telescopic instrument, which is today vital, was invented by Galileo Galilei in 1609, although other inventors had also developed comparable devices at the time. Radio telescopes, spectroscopes, and star charts are all examples of astronomical instruments.

What are the 3 main types of telescopes?

In general, there are three types of telescopes. Refracting telescopes, Newtonian telescopes, and Schmidt-Cassegrain telescopes are the three types of telescopes.
