a refractor uses a lense, a reflector uses two mirrors, IS THAT SIMPLE ENOUGH?!

The largest visible light telescopes are now all what?
reflectors
What kind of telescope's objective is a lens but contains no mirrors?
Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)
Do Professional astronomical telescopes generally have a much greater magnification than the telescopes you can buy in stores?
Nope. they dont.
Which type of telescope was invented first?
The telescopes used by Leeuwenhoek, Huygens, and Galileo were refractors. Newton fashioned the first reflector, with a primary mirror of made polished brass.
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 are 2 types of telescopes?
Refractors (with lenses)Reflectors (with mirrors)
The largest visible light telescopes are now all what?
reflectors
Why is it a advantage for reflecting and refracting telescopes to be made larger?
The reason people build larger Telescopes is because smaller telescopes have a smaller power to them, which results in less detail the farther they look. Larger telescopes use much larger lenses to see much farther and with much more clarity.
Where can one purchase astronomical telescopes?
Many companies sell astronomical telescopes for purchasing. Companies that sell this product include Amazon, Orion Telescopes & Binoculars, and Young Explorers.
Where do reflecting telescopes work best?
All telescopes work best in the vacuum of space. Aside from that, "where" really is not a great factor compared to other types of telescopes. The distinct advantage of some reflecting telescopes is that they don't suffer from chromatic aberration like refractors do.
Why do scientist prefer refracting telescope over reflecting telescope?
Reflecting telescopes give a brighter, clearer image that refraactors in many cases. Add to that the fact that refractors become very impractical with objective lens sizes much above 40 inches, while reflectors can have mirrors of 200 inches and more.
What kind of telescope's objective is a lens but contains no mirrors?
Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)
Who built and used reflecting telescopes?
Thousands of people still do build their own astronomical telescopes; it isn't that hard to do.
Do Professional astronomical telescopes generally have a much greater magnification than the telescopes you can buy in stores?
Nope. they dont.
What telescope uses mirrors to bounce light toward the eyepiece?
Reflecting telescopes do this. There are many different kinds of reflectors.
What is better Reflecting or refracting telescopes?
The most serious astronomical research, such as that done by the Hubble Space Telescope, is done with reflecting telescopes.
What is A place at which stars are studied with the help of telescopes?
An "observatory".
