Physics for Kids A telescope is an instrument used to see objects that are far away. Telescopes are often used to view the planets and stars. Some of the same optical technology that is used in telescopes is also used to make binoculars and cameras. 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. 2  This feature is usually determined by the size of the aperture of the telescope. 3  The larger the aperture, the more light the telescope can gather.

Infrared telescope An infrared telescope is a telescope that uses infrared light to detect celestial bodies. Infrared light is one of several types of radiation present in the electromagnetic spectrum. All celestial objects with a temperature above absolute zero emit some form of electromagnetic radiation.

- That's because a telescope with a larger diameter can gather much more light, give a brighter image, and be useful at a higher magnification. For ordinary daytime terrestrial viewing, where lots of light is available, you really don't need a lot of aperture.

- The word telescope is a noun that refers to a device for collecting light or other electromagnetic radiations and focusing it in such a way as to be able to visualize objects … that are very far away. The word telescope is also a verb that describes the action of a long object collapsing in a specific fashion into a shorter object.

Why do astronomers put telescopes in space? If you are in …space you do not have this distortion. The Hubble Telescope is a good example of space based telescopes. Scientists have put telescopes in space to avoid interference by the atmosphere.

- Many celestial phenomena can be seen at more than one wavelength. 1  Optical telescopes can be used on Earth and in space. An example of a huge optical telescope in space is the Hubble Space Telescope through which astronomers can look out across the Universe without the distortion of light by the Earth's atmosphere. The first optical telescope was created 400 years ago, while the other kinds of telescopes were invented in the 20th century.

Reflecting telescope A reflecting telescope is a telescope that uses a single or combination of curved mirrors that reflect light and form an image. The reflecting telescope was invented in the 17th century,by Isaac Newton, as an alternative to the refracting telescope which, at that time, was a design that suffered from severe chromatic aberration. Although reflecting telescopes produce other types of optical aberrations, it is a design that allows for very large diameter objectives. Almost all of the major telesco

Mirrors and Lenses Chapter 14 Science a telescope which uses one concave mirror, one plane mirror, and one convex lens. It collects and focuses light to help see distant objects.

The Differences Between Microscopes and Telescopes Basic Differences. Although both instruments magnify objects so that the human eye can see them, a microscope looks at things very near, while telescopes view things very far away. Microscopes are commonly found in laboratories, often used by biologists and chemists, while telescopes are found in observatories, most often used by astronomers.

Telescopes Such an arrangement, called a newtonian design is used by many amateur telescopes. Many reflector telescope use another light path design called the cassegrain design to reflect the light back through a hole in the primary mirror, so that detectors or the eyepiece can be conveniently placed behind the telescope.n both the reflector and refractor telescopes, the focus is before the eyepiece, so the image in astronomical telescopes is upside down. Telescopes used to look at things on the Earth's surface use another lens to re-invert the image right-side up.

How does a telescope work? This illustration shows how light enters a reflector telescope. Optical telescopes allow us to see further; they are able to collect and focus more light from distant objects than our eyes can alone. This is achieved by refracting or reflecting the light using lenses or mirrors.

What is the difference between a refracting telescope and a reflecting telescope? A refracting telescope uses glass lenses to bend the light into an image (similar to a magnifying glass) and is a very common style of telescope. A reflecting telescope on the other hand uses a concave mirror (similar to the mirrors that you can buy that enlarge sections of your face) to magnify the image. They each have their advantages, a refracting telescope is easier to manuever and produce, while a reflecting telescope can be made much larger (due to the fact that you can support the underside of the mirror).

High School Earth Science/Telescopes 1 Radio telescopes collect and focus radio waves from distant objects. 2  Space telescopes are telescopes orbiting Earth. 3  They can collect wavelengths of light that are normally blocked by the atmosphere. 4  Galileo was the first person known to use a telescope to study the sky.

telescope These telescopes use a concave mirror (usually parabolic) as the objective. They are called reflecting telescopes. Light from a distant object is collected by the large concave mirror and reflected onto a small mirror (positive in the Cassegrain telescope and negative in the gregorian telescope).

Optical telescope catadioptric telescopes, which combine lenses and mirrors; A telescope's light gathering power and ability to resolve small detail is directly related to the diameter (or aperture) of its objective (the primary lens or mirror that collects and focuses the light). The larger the objective, the more light the telescope collects and the finer detail it resolves.

Reflecting Telescope Facts Reflecting Telescope Facts. A reflecting telescope is one that causes an image to reflect at a focus point by using mirrors. It was invented during the 1680s by Isaac Newton. These telescopes improved the before used refracting telescopes by giving a clearer picture.eflecting telescopes are also called reflectors. Most telescopes used by astronomers today are reflectors. In Newtonian telescopes, one mirror is used to capture the image while another mirror is used to reflect the image from the first mirror.

telescope These telescopes use a concave mirror (usually parabolic) as the objective. They are called reflecting telescopes. Light from a distant object is collected by the large concave mirror and reflected onto a small mirror (positive in the Cassegrain telescope and negative in the gregorian telescope). This mirror is located on the optical axis and light is then transmitted through a central hole in the concave mirror onto the eyepiece.

Refracting Telescopes Galileo is credited with being the first person to use a telescope to make observations of the night sky. After hearing of the invention of the telescope in 1608, he built one of his own, called a Gallilean Telescope, in 1609 using a convex objective lens and a concave eyepiece lens. His telescope could magnify objects 3 times. Telescopes he made later magnified objects up to 30 times.
