How does a infrared telescope work?
A refracting optical telescope uses two lenses, like magnifying glasses, to gather and focus the light carrying the images of the target that's being observed. The first lens is called the primary lens. It's the larger of two lenses. It's located at the far end of the scope away from the eyepiece where the observer will sight the target. The target's light enters the scope through the primary lens. The Yerkes Observatory in Wisconsin USA is the largest refracting telescope. It's primary lens is a tad over 1 meter in diameter. The eyepiece at the near end is the second lens. It takes that gathered light from the primary lens, and focuses and magnifies it even further. So whatever the target might be is magnified many times over. First by the larger lens and then again by the smaller eyepiece lens. So, for example, if the primary lens magnifies by 5X and the eyepiece does it by 10X, the overall magnification is 50X. The two multiply.
What are the ways have worked around the problems of optical telescopes?
Images from outer space have to go through the atmosphere in order to reach telescopes based on Earth. The atmosphere can distort and block light and thus obscure the images. Telescopes based in space, such as the Hubble, don't deal with this limitation.
What is a good telescope for a junior astronomer?
A good telescope for a junior astronomer would be one that is easy to set up and use, such as a Dobsonian telescope. Look for a telescope with a simple design, good optics, and a sturdy mount. Consider a telescope with a moderate aperture size (4-6 inches) to balance performance and portability for a beginner.
How you observe the sun planets and stars?
Observing the Sun, planets, and stars can be done using telescopes that are designed for each type of observation. Solar telescopes have special filters to safely observe the Sun's surface. Planetary observations can be made using telescopes and cameras to capture images and details. For stars, telescopes are used to observe their brightness, color, and motion in the sky.
What are the advantages and disadvantages of a refracting telescope?
Advantages of a refracting telescope include excellent image quality due to the lack of central obstruction, making them ideal for observing high-contrast objects like planets. However, they are more sensitive to chromatic aberration, which can affect image clarity and color accuracy. They are also more expensive to build for larger apertures, and they tend to be longer and bulkier compared to reflector telescopes.
What advantage might a mountaintop telescope have over a city telescope?
Mountaintop telescopes don't have to deal with the light from the city, so they get more of a clear night sky.

Why do non optical telescopes work better on earth?
They don't. All earth bound telescopes, optical or not, must deal with a number of issues. But what do you mean by "better"? A radio telescope is better suited to pick up radio waves than an optical telescope, but an optical telescope is better for visible light. They each serve their purpose better than the other.
Does deal have a long or short vowel sound?
"Deal" has a long vowel sound, as in the word "feel."
How are a microscope and telescope alike how are they different?
Microscopes and telescopes that work with visible light are both devices to collect and magnify light. Id you talk about refracting telescopes, which are the most like microscopes because they use lenses in a tube, you could thing of a microscope as looking in one end and telescope as looing in the other end to deal respectively with the very small and the vary far away.
What are the disadvantages of the orbiter?
They do not have to deal with the optical distortion otherwise cause by our atmosphere. Also most locations of earth could never have a major telescope because of light pollution, not an issue in space. ____________________ Some disadvantages are that they are costly to maintain and to operate.
What are some jobs that have to deal with cells or weather or even sound?
A meteorologist deals with weather, a scientist, a dentist, a doctor or anything like that would deal with cells and a DJ would deal with sound
How can a sound continue to be heard after a sound source stops making the sound?
Sound is your eardrum detecting a pressure wave in the air, this wave takes time to get from the source to your ear (about 340 metres per second). light, however travelles a great deal quicker ( 300000000 metres per second) than sound, so you see the cause before you hear it.
Does the frequency of a sound wave deal with the volume of the sound?
No. Frequency is related to pitch, and amplitude is related to volume.
Where can I get the best deal on high quality surround sound speakers for a multimedia computer?
The unarguable best place to purchase great quality surround sound speakers and compounded with a fantastic deal is on this site - a must for all deal savvy people.

What does the science of optics deal with?
It deals with light.
