What uses mirrors to focus light from the object being viewed a refracting telescope or a reflecting telescope?

A reflecting telescope uses a curved mirror to concentrate the light from distant stars, and is a very useful technique. There are very clever techniques and technicians, which can produce a mirror perfect over all its area, to within part of the wavelength of light!!
The alternative method of using a glass lens, suffers from various difficulties, such as distortion and loss of light.
You do not ordinarily consider focus in an astronomical telescope, for all the stellar objects are essentially at infinity.

What are some similarities and differences between refracting and reflecting telescopes?
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
How does the refracting telescope work?
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.
What is a telescope that uses an object lens to bend light toward the plane where the image is found?
reflecting telescope
Why are most large telescopes reflecting telescopes?
They are refracting telescopes(:Large refracting telescopes are no longer built because there were too many problems with them. There was color distortion, light pollution, and when the object hits the focal point it turns upside down. Then you don't see the object for what it really is, you see it upside down and weird-ed out. They are to complicated and scientists believed they should just stick with the simple, small, original refracting telescopes!!!!-Meghan Betts (8th grader)
What does a telescope reflect?
A reflecting telescope is an optical telescope which uses mirrors to bring the light to a focus. The first one was designed by Isaac newton.
What advantages do reflecting telescope have over refracting telescope?
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 objective of a refracting telescope do?
It gathers the light coming from an object.
What is the difference in refracting and reflecting telescopes?
A refracting telescope uses a series of lenses to magnify the light - like a simple spyglass, or a pair of binoculars. A reflecting telescope uses a concave mirror to gather light, which comes to focus at a point somewhere out in front of the mirror. It is then reflected sideways by another mirror into an eyepiece, which magnifies it. A refractor gives a bigger, but dimmer view of the distant object. A reflector gives a smaller, but brighter view of it.
What is the light that strikes a reflecting or refracting material called?
Light. Quantum particles impeding on an object. Electromagnetic waves striking an object.
What is a telescope that uses an object lens to bend light toward the plane where the image is found?
reflecting telescope
One function of a refracting telescope?
The nominal function of any telescope is to enlarge the image of a distant object and that is the same for reflecting or refracting or hybrid telescopes. That said, it is a better description of a telescope to say it is a light collector that brings into an image (on the eye or photo sensor of the user) the light that is given off by some distant object. The aperture of a telescope is much much larger than the aperture (iris) of the human eye, so whatever object is being viewed is producing light an a much greater quantity of light is entering the telescope than would be entering the eye. More light allows the image being viewed to be enlarged and still visible to the human eye.
What is the main purpose of object lenses concave mirrors in the telescope?
Magnify images
