Reflecting telescopes differ from refracting telescopes in having?
Reflecting telescopes use mirrors to gather and focus light, while refracting telescopes use lenses. Reflecting telescopes tend to be more compact and easier to support larger apertures, making them popular for professional astronomical research. Additionally, reflecting telescopes are less affected by chromatic aberration compared to refracting telescopes.
Why do optical astronomers place telescopes at the top of mountains while radio astronomers put their telescopes in valleys?
Optical telescopes are placed high to avoid having to look through the thickest part of the atmosphere. Radio telescopes are place in valleys to avoid the effects of man-made electrical noise in the telescope.
What is the meaning of reflector?
One who, or that which, reflects., Something having a polished surface for reflecting light or heat, as a mirror, a speculum, etc., A reflecting telescope., A device for reflecting sound.
What are 2 reasons for sending telescopes into space?
Telescopes in space are able to view objects clearly without having to look through a thick layer of the Earth's atmosphere. This enables them to capture better pictures and observe dimmer and more distant objects.
How do shrimps and crabs differ from snails clam and oyster?
Shrimps and crabs differ from molluscs by having a chitinous exoskeleton and jointed appendages.
What does you beg to differ mean?
When you are having a polite disagreement with someone.
What is the advantage of having telescope that collect and focus radiation?
All telescopes collect or focus radiation in some way, because visible light is a form of electromagnetic radiation. The advantages of telescopes include being able to see things that are far away, as well as the ability to observe heavenly bodies.
What is a disadvantage of having a telescope in a desert?
Most telescopes in the desert are quite a distance from towns and cities which means that scientists and technicians must travel to reach them or to obtain supplies.
Which description most likely fits a nocturne?

How are lampreys different from hagfishes?
Lampreys differ from hagfishes by having a notochord that is surrounded by a tube of cartilage.
Why is it an advantage to have telescopes on the ground?
This is because they are easier to mantain as it does not require launches to get astronaughts up there to fix them. Also they are cheaper having to make a telescope usable in space takes time and money, it also requires a launch which is expensive as well. It is easier to view the results as you can view them directly form the telescopes, instead of them having to be sent from space down to earth using microwaves then you need an antana and other equipment to view it.
Most optical telescopes used by professional astronomers are in?
Most optical telescopes used by professional astronomers are located on mountains or remote locations away from city lights to minimize light pollution and atmospheric disturbances. Some observatories, such as those in Chile and Hawaii, are known for having excellent observing conditions due to high altitudes and clear skies. Telescopes are also placed in space, like the Hubble Space Telescope, to avoid atmospheric interference.
