Reflecting Telescopes Are Popular Because They're

A. The VLT (Very Large Telescope) is the world's largest telescope and it is taking scientists further back to the Big Bang than they ever thought possible. Domestic rats aren't the same as the ones that run around rubbish bins — they're actually quite cute. They are very intelligent and can be trained like...Reflecting telescopes are popular because they're smaller and compact compared to refracting telescopes. This allows astronomers to break them down and carry them to other locations quite easily. It's important to be careful with the mirrors, though. They can be knocked out of.A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. Refracting telescopes put a very serious limitation on how large the telescope's aperture can be because they require a large area of unsupported glass.G. The popularity of text messages led to the development of a special system of words or 'chat speak'. For example, acronyms, that are words made from the first letters of other words, are often used both in online chatrooms and text messages sent to your mobile phone.These telescopes are relatively easy to use because they produce an image that is shown the correct side up left to right. However there's absolutely nothing wrong with refracting telescopes. They're great for beginners as they do a pretty good job and don't require much maintenance at all.

easier to build than a refracting telescope.Parrots are popular pets. This is because they are very bright and look beautiful. It is not a good idea to get only one bird. Parrots may get ill if they feel lonely because they are social birds. A pet parrot will certainly give you a lot of positive emotions.Different telescopes are optimized for different purposes. The trade-off is severe, however. And for objects in our own Solar System, because they reflect sunlight rather than emit their own, self-generated light, they cannot be seen by any modern telescope if they're located beyond a certain...Big mirrors used in reflecting telescopes are easier and cheaper to make than big lenses which would cost more because of the quality of glass required to make refracting telescopes.

Reflecting telescopes are popular because they're than a refracting...

Start studying Refracting and Reflecting telescopes. Learn vocabulary, terms and more with flashcards, games and other study tools. While the refracting telescope uses a lens, that you can see through, the reflecting telescope a mirror. They are both curved, but they display different...The main reason for it is that many people often go to the library because it is the only free source of books they have. At the same time some people consider that libraries belong to the past and they lose their popularity.They're my best ones, so I put them on only for special occasions. KEYS.

Reporter: The Walkie Talkie has been blamed for reflecting light which melted parts of a car...A reflecting telescope (also called a reflector) is a telescope that uses a single or a 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...a) The reflecting telescopes are preferred over refracting type because of the following reasons: (i) There is no chromatic aberration in case of reflecting telescopes as the (ii) Spherical aberration is reduced in case of reflecting telescopes by using mirror objective in the form of a paraboloid.

If if truth be told one have been to adopt to build a telescope, one would undoubtedly make a selection to grind the mirrors of a simple Newtonian reflector quite than attempt to grand the lense of a refractor, but I doubt that that would make it the more popular, so that eliminates C. Given that both telescope have the same diameter object lens or mirror, they are both equally robust, so that eliminates A. A newtonian reflector is under no circumstances tougher than a refracting telescope the mirrors must be ceaselessly realigned, in order that removes D. B is the one solution left and I will have to agree that is a logical solution because for a given diameter, the reflector will certainly be more compact. But I believe they are more popular because for a given diameter they are a lot more cost effective. An Eight inch reflector costs about 00 however an 8 inch refractor would value a small fortune and require a special development to house.
