What is the difference between refract and reflect?
Reflection is where the light hits the surface and `bounces` back off the surface, while refraction is where the light enters the medium and changes direction according to the refractive index of the medium. The higher the refractive index, the more the light is refracted.
What do scientists build telescopes on top of?
Some telescopes are on the earth this is because they are easier to maintain 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 from the telescopes, instead of them having to be sent from space down to earth using microwaves then you need an antenna and other.
What is a disadvantage of having a telescope in space?
There are also disadvantages of having telescopes in space 1 is that they are expensive to run and maintain each launch can cost millions of dollars and building the telescope can cost many million as well. Transmitting the information to earth can take longer then telescopes on the ground and can require more power.
How do ions differ from nonpolar molecules?
ions it may be positive charge or negative but nonpolar is having same charge like H2 IS NONPOLAR AND HCL IS POLAR............
Why does photographs from telescopes in space show the nebula more clearly?
Space-based telescopes can see further in space as they don't have to make do with a disturbing atmosphere (slight differences in temperature in atmospheric layers lead to perturbations of photos). So, very long exposures (over hours) can reasonably be made without having to fear such undesired phenomena. Very long exposures also means that the very faint sources of light (at the edge of the observable universe) can also be pictured so that they can be distinguished from the background noise. This way, space telescopes see further.
Reflecting telescopes differ from refracting telescopes in having what?
Two large objective lenses.
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.
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.
Which description most likely fits a nocturne?
A poem about having trouble sleeping
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.
How may atoms of the same element differ from one another?
Atoms of the same element may differ from one another by having differing numbers of Neutrons in their centres.
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.
How are lampreys different from hagfishes?
