Can anyone describe the refracting telescope to me?
Mystic Swordman Lv4 asked:
I need information on the refracting telescope for my school project. Please include a diagram (labeled) and description of how it works. Also, explain its uses in the world, and how are they useful. Finally, include references so I can refer to them later.

Refracting telescopes (or refractors) use lenses to gather and bend light making things seem larger. The lenses used in refracting telescopes are called concave and convex. Convex (curved outward) lenses make things bigger, but blurry. Concave (curved inward) lenses make things look clearer, but small. As you can guess, a combination of these two lenses makes things seem bigger and clearer.
Imagine we are still outside looking at Venus with a refracting telescope. What happens when you look through the telescope? An objective, or large, lens collects light from Venus and sends it to a smaller, eyepiece lens at the back of the telescope tube. The eyepiece magnifies the little image of Venus and directs it at your eye. Wow, can you see the yellow-white disk? Now that’s some planet!
Check out the website for the diagram.
Hope this helps! Bruce

Jeez Bruce, are you doing this guy’s homework. Bloody nerve of the guy - even wants diagrams, though how he thinks that could be done through this medium.
Do some reading you lazy sod. nick s

Sounds like you want us to do all your homework for you, while you get the credit without having to do the work or learn anything. Wikipedia has information on refracting telescopes, you can create your own diagram (or steal one) from telescope manufacturer websites (like Tasco or Schmidt-Cassegrain), and even with just a little thought you can come up with uses. lindajune
