A reflecting telescope is much easier to build than a refracting telescope and consequently is much less expensive. A reflecting telescope uses a concave mirror to collect and concentrate starlight and send it to your eye, whereas a refracting telescope uses a series of lenses to do the same thing. Optical quality lenses are much more expensive (and heavier) than a well-made mirror. For a given amount of money, much larger reflecting telescope can be built than a refracting. For very large telescopes, the lenses needed would be enormous and next to impossible to make optically perfect. Consequently, most telescopes are reflecting.
Reflecting telescopes are popular because they are easier to build than refracting telescopes.
They are more durable than a refracting telescope.
reflecting telescopes have concave lenses and refraccting telescopes have convex lenses.
Light is found by reflecting telescopes and refracting telescopes are used to dected sound
No
no, reflecting telescopes.
A mirror instead of and objective lens (:
The most serious astronomical research, such as that done by the Hubble Space Telescope, is done with reflecting telescopes.
reflecting telescopes have concave lenses and refraccting telescopes have convex lenses.

No
they the same
no, reflecting telescopes.
reflecting telescopes
They have many other different types of telescopes than just reflecting!!!! I have a refracting telescope myself. They also have other things like binoculars and microscopes
Two large objective lenses.

Yes, both of them. And they also use reflecting telescopes.
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.
