Which of the following statements best describes the two principal advantages of telescopes over eyes? Telescopes can collect far more light with far better angular resolution. … It is the best angular resolution the telescope could achieve with perfect optical quality and in the absence of atmospheric distortion.
Which of the following is a principal advantage of CCDs over photographic film quizlet?
Which of the following is a principal advantage of CCDs over photographic film? CCDs capture a much higher percentage of the incoming photons than does film.
What wavelength regions can be studied with telescopes on the ground of earth?
Which of the following wavelength regions can be studied with telescopes on the ground? A. infrared, visible, and ultraviolet light.
What do astronomers mean by light pollution group answer choices?
What do astronomers mean by light pollution? Light pollution refers to light used for human activities that brightens the sky and hinders astronomical observations.
What are the two most important properties of a telescope?
The two most important properties of a telescope are:
- Light gathering ability – The better a telescope can gather light, the better you will be able to see far away stars and faint objects in the night sky. …
- Magnification – The magnification of a telescope describes how much larger the telescope can make objects appear.
Which of the following statements best describes two principal advantages of telescopes over eyes?
Which of the following statements best describes the two principal advantages of telescopes over eyes? … Telescopes can collect far more light with far greater magnification. Telescopes collect more light and are unaffected by twinkling. Telescopes can collect far more light with far better angular resolution.
What is the primary advantage of CCDs over the photographic plate?
7. One of the primary advantages of CCDs over photograph plates is their high efficiency in detecting light. 8. The Hubble Space Telescope can observe objects in the optical, infrared, and ultraviolet parts of the spectrum.
Which electromagnetic radiation wavelength is efficiently observed using ground-based telescopes?
It might be surprising to know that astronomers can use ground-based astronomy to detect the highest energy gamma-rays. For these gamma-rays, the telescopes don’t detect the gamma-rays directly. Instead, they use the atmosphere itself as a detector. The HESS array has been in operation for over 10 years.
What wavelengths can be studied from Earth?
From Earth we can study the optical and radio wavelengths fairly easily. We can see a little infrared in precision observatories and a miniscule fraction of ultraviolet – this is what gives us a tan in the sun. The light that we see from stars is just one form of observing we can do.
Which of the following forms of light can be observed with telescopes at sea level?
Which of the following forms of light can be observed with telescopes at sea level? Both visible light and radio waves pass almost freely through Earth’s atmosphere, and therefore are easily observed with ground-based telescopes.
Which of the following wavelength regions of light can be studied with ground based telescopes quizlet?
It reduces blurring caused by atmospheric turbulence for telescopes on the ground. It reduces blurring caused by atmospheric turbulence for telescopes on the ground. Which of the following wavelength regions can be studied with telescopes on the ground? infrared, visible, and ultraviolet light.
Why do astronomers build observatories for optical telescopes on top of mountains in the desert Choose all that apply?
Optical astronomers put their telescopes on top of mountains to get above the cloud level (as far as possible) and to get away from the light pollution of cities so as to get the best view of the night sky.
Which of the following are forms of light electromagnetic radiation )?
-X-rays and radio waves are both forms of light, or electromagnetic radiation.
What advantages come from putting a telescope in space?
Space telescopes have the advantage of being above the blurring effects of the Earth’s atmosphere. In addition, there are many wavelengths from the electromagnetic spectrum that do not reach Earth because they are absorbed or reflected by the Earth’s atmosphere.
Which of the following is the most important feature of a telescope?
Aperture: A Telescope’s Most Important Feature
The most important characteristic of a telescope is its aperture — the diameter of its light-gathering lens or mirror, often called the objective. Look for the telescope’s specifications near its focuser, at the front of the tube, or on the box.
What is the importance of telescope?
The telescope is undoubtedly the most important investigative tool in astronomy. It provides a means of collecting and analyzing radiation from celestial objects, even those in the far reaches of the universe.
