How are reflecting and retracting telescopes different?

A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.

Does a telescope use a convex lens?

Reflecting telescopes don't use lenses - they use mirrors (hence 'reflecting'). Light goes in the top, hits a concave mirror at the bottom of the tube which makes the light converge when it is reflected, then bounces back up to the top where it hits a smaller secondary mirror, where it is directed down the eyepiece. Do you mean refracting telescopes? If so then these do use lenses, the amount depends on the telescope. The most simple form has an objective lens which focuses the light, and then an eyepiece which has a lens in it to magnify the image. The objective lens is convex on the side pointing out of the telescope, and is flat on the other side.


What telescope collects light with a mirror?

The type of telescope is called a reflector. There are multiple subtypes of reflectors like a dobsonian, newtonian, RC, etc. Check out my youtube video on how to work with pictures taken from a telescope. youtu.be/M7-vLeVhM9g


What kind of telescope uses both a reflecting mirror and a refracting lens to produce wide angle photos of the sky?

A reflecting telescope has both magnifying mirrors and lenses to focus the image on the eyepiece. A refracting telescope uses only lenses to magnify and focus. A reflecting telescope can be much smaller, because the light can travel through the barrel of the telescope several times, being magnified with each reflection. This is why most large modern telescopes are reflectors.


What is the name of the telescope that uses convex lenses to gather and focus light?

Refracting telescope.

Why do reflecting telescopes use con cave mirrors and not convex mirrors?

Convex mirrors spread and not focus light. They do the opposite of concentrating and magnifying. They are the mirror image of what a concave telescope is and does. Pun intended.
