Do refracting and reflecting telescopes use visible light to view the images?
Those terms are most commonly used for optical telescopes. However, the same design can be used for non-visible frequencies; for example, radio telescopes of the "satellite dish" variety are essentially reflecting telescopes.
What are two different types of telescopes?
Refractors and reflectors. One should add the largely Russian-developed Cassegrainean combines features of both systems-called also Maksutov after its Russian inventor who was awarded the Staliln Prize for this feat. They are adapted to (Mirror=Lens) telephoto camera lenses, also.
What are the 5 main main telescopes used to gather information about the universe?
Optical (refracting and reflecting types), Radio, Infra-red, X-ray, Gamma-ray. Some of these need to be carried on satellites as the atmosphere absorbs the radiation under study - fortunately for us!
Which is bigger a reflecting or refracting telescope?
There is no single answer to this question. The Cassegrain has a paraboloidal shaped main mirror. The Ritchey-Chrétian has a hyperboloidal main mirror. I have a Schmidt-Cassegrain which has a spherical main mirror. Dall-Kirkham telescopes have an ellipsoidal main mirror. The secondary mirror can have different shapes as well but I won;t get into hose. That's a separate issue.
Are x-ray telescope mirrors similar to optical telescope mirrors?
The biggest telescopes are reflecting - instead of a main lens, they have a main mirror. Above a certain size, it is no longer feasible, or at least practical, to use lenses.The biggest telescopes are reflecting - instead of a main lens, they have a main mirror.

What is catadioptric telescope?
Basically, the catadioptric telescope is just one of the 3 main types of the optical telescopes.The other 2 main types of optical telescopes are the refracting telescopes and the reflecting telescopes.
What are the major types of optical telescopes?
Ground-based telescopes, and space telescopes. Or: refracting telescopes (main collector is a lens), and reflecting telescopes (main collector is a mirror). Or: Home telescopes (small ones), and professional ones (larger and more expensive).

What are some telescopes names?
The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.

What is the second lens in a traditional refractor called?
Refracting telescopes use a main lens made from glass and called the objective lens.
Is a light telescope the same as a refracting telescope?
Not exactly. A light telescope is a telescope that catches and shows visible light. The main light-gathering piece may either be a lens, in which case you would have a refracting telescope. Or - much more common with the larger telescopes - the main light-gathering piece is a parabolic mirror. In this case, it is a reflecting telescope. The largest refracting telescope is about 1.2 meters in diameter; all larger telescopes - currently up to about 8 meters - are parabolic mirrors.

What is the meaning of refracting telescope?
That means that it uses lenses that use refraction to change the direction of light. More specifically, the main light-gathering piece is a lens - as opposed to a reflecting telescope, which uses mirrors for this same purpose.
