Why aren't infrared telescopes built at low altitudes?
Infrared telescopes are usually built at high altitudes to minimize atmospheric interference. At lower altitudes, the Earth's atmosphere absorbs and scatters infrared light, making it difficult to observe astronomical objects accurately. By placing telescopes at high altitudes, such as on mountain peaks, scientists can minimize the interference and obtain clearer observations of infrared radiation from space.
What magnification power does a scanning lens have?
Most light microscopes have 10X eyepieces.
What is the use of telescope in ornithology?
Ornithological telescopes allow bird-watchers to observe birds from a distance, so there is less risk of frightening them away. Since they require a tripod, they are generally heavier to carry than binoculars, but binoculars are more difficult to use since they are more difficult to hold still and steady for any length of time. Also, telescopes are capable of greater magnification than binoculars.
How are reflecting and refracting telescopes different?
Reflecting telescopes use mirrors to collect and focus light, while refracting telescopes use lenses. Reflecting telescopes typically have a closed tube design which protects the mirrors from dust and other contaminants, while refracting telescopes are more prone to chromatic aberration. Reflecting telescopes are generally easier to manufacture at larger sizes compared to refracting telescopes.
Compare reflecting and refracting telescopes?
Reflecting telescopes use mirrors to collect and focus light, while refracting telescopes use lenses. Reflecting telescopes are typically less affected by chromatic aberration, while refracting telescopes can be more prone to this issue. Reflecting telescopes are generally more cost-effective for larger apertures.

Where are telescopes found?
Optical telescopes are found through out the world. They have even been taken to space as in the Hubble Telescope. The Optical telescope is the main telescope used by amateur astronomers. They are used in Gardens through out the world. Professional optical telescopes are generally placed on the very top of mountings. This is to reduce the amount of distortion caused by the atmosphere. The Keck observatory for example is at an altitude of 4.2 km atop the summit of Mauna Kea on Hawaii.
What kind of microscope is used for microsurgery?
A magnification of five to forty times (5-40x) is generally required for microsurgery. A lower magnification may be used to identify and expose structures, while a higher magnification is most often used for microsurgical repair.

What is the difference between a refracting telescope and a?
A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens. A reflectortelescope uses a mirror as its objective. The mirror is close to the rear of the telescope and light is bounced off (reflected) as it strikes the mirror
What happens to the field of view as magnification increases?
As magnification increases, the field of view generally decreases. This is because higher magnification typically focuses on a smaller area in greater detail, limiting the overall visible area in the field of view.
What is the name of a placethat uses telescopes and other scientific eguipment to research space and astronomy?
An observatory is a place that uses telescopes and other scientific equipment to research space and astronomy. These facilities are typically located in remote areas with minimal light pollution to allow for optimal observation of astronomical phenomena.
How long has the telescope been around?
The invention of the telescope is generally attributed to Hans Lippershey in 1608. The first practical telescopes were developed by Galileo Galilei in 1609. So, telescopes have been around for over 400 years.
