Do telescopes use a reflecting mirror to focus light onto a small area?

Many telescopes do, especially the largest ones.
Others use a refracting lens to do that job.
(Note: Our entire discussion so far has included a redundant amount
of redundancy. All mirrors reflect, and alllenses refract.)

Differences between reflecting and refracting telescopes?
Reflecting Telescopes -uses a single or combination of curved mirrors to bring light to a focus and make an image.
What type of lens is used in the eyepiece for reflecting telescopes?
A radio telescope is a reflecting telescope, and uses a mirror rather than a lens. Since radio waves are so much longer than light waves, the 'mirror' of a radio telescope is the 'dish' reflector that focuses radio waves onto its antenna, located at the prime focus of the dish.
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.
What is the difference between refracting telescopes and reflecting telescopes?
Hi , A reflective scope uses mirrors to focus the image and the light while a refractive scope uses curved glass lenses to focus the light and the image. Generally the reflector telescope is better for deep sky viewing and the refractor is better for lunar and planetary viewing. You can also find a compound telescope which uses both glass and mirrors which is better for general viewing.

What is the difference between a reflecting telescope a refracting telescope and a radio telescope?
Reflecting telescopes are usually designed to capture and concentrate light through the use of a large concave mirror which focuses the captured light on a smaller, flat mirror which in turn reflects it to the eye or a camera. Refracting telescopes use convex lenses to capture light and focus it where the eye or a camera is. Radio telescopes collect long wavelength radiation (radio waves and microwaves) and are all forms of reflecting telescope. The first telescopes were refracting telescopes, because the technology existed to form the needed sizes of convex lenses. Reflecting telescopes were developed later, when advancing technology provided the means of making very regular concave mirrors. All the largest modern telescopes are variations on the reflecting telescope design because it is easier to make and manage very large concave mirrors than it is to make lenses of equivalent light collecting power.

When light strikes the large concave mirror of a reflecting telescope where is the light focus?
In front of the mirror
What uses two lens and mirror?
Reflecting TelescopeA reflecting telescope uses a lens and two mirrors. The lens is positioned at the eyepiece, and thus the focus, which the two mirrors generated by specifically redirected light. There are two types of reflecting telescopes with one lens and two mirrors, the Newtonian Focus and the Cassegrain Focus.
What advantage do reflecting telescopes hAve over refracting telescopes?
One advantage of reflecting telescopes is that the mirrors can be very big. Large mirrors allow reflecting telescopes to gather more light than refracting telescopes do. Another advantage is that curved mirrors are polished on their curved side, which prevents light from entering the glass. Thus any flaws in the glass do not affect the light. A third advantage is that mirrors can focus all colors of light to the same focal point. Therefore, reflecting telescopes allow all colors of light from an object to be seen in focus at the same time.

What does the reflecting telscope do?
They use a mirror instead of a lens to focus light into the eyepiece. Newtonian telescopes are the most common type. Schmidt-Cassegrain is also a popular design but more complex and expensive.
