Galileo did not invent the telescope. The Italian physicist and mathematician improved on an existing spyglass design to create a more powerful one: a refracting telescope that he then used to study the night sky.
He didn't he improved the existing telescope and turned it to astronomical use around 1609
It would be reflection, if you are doing a study island test. :)
Mirrors and telescopes use light reflection.
The sources of Galileo is he wasn't the inventor of the telescope,but he was the first to use the telescope. Also he improved the telescope making an object look about 20 times bigger.Also,he made it magnify 3 times as much as before made this improvement in 1608-1609.

Some design variants you may see in an optical telescope include telescopes that fold or divert the optical path with mirrors and telescopes that use special lenses to enhance the images.

It all depends on if the telscope is a refractor, or a reflector. Reflectors have a convex mirror that bends the reflection on to a flat mirror that angles the magnified reflection to the eyepiece. Refractors use to convex lenses that bend the image and light, magnifying the view to the eypiece.
The Hubble telescope was launched in 1990, but faulty optics limited its use until a shuttle mission made repairs in 1993. Other servicing missions improved its onboard instruments. It will be mostly superseded by the James Webb Space Telescope planned for launch around 2018.
The instrument scientists use to observe the planets is a high powered telescope.

The word 'telescope' is a noun.Example: "I don't know how to use a telescope."
