What shape mirror is used to collect light in a reflecting telescope?

It's definitely concave, and up until recent times, it was always parabolic. Modern
optical techniques, bordering in this contributor's view on the black magic, now
make it possible to make the mirror's 'figure' spherical, with the resulting ray
bundle then 'corrected' by more mirrors of various shapes later down the line.

Does a reflecting telescope gather light with a lens or a mirror?
reflecting telescope gathers light from mirror
How is a radio telescope similar to a refracting telescope and a reflecting telescope?
They all collect and focus light and other forms of electromagnetic radation.
What is used in a telescope to reflect light?
Reflecting telescopes use mirrors to collect light.
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 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.

Which type of telescope uses a mirror to gather light?
A reflecting telescope.
When light strikes the large concave mirror of a reflecting telescope where is the light focus?
In front of the mirror
When light strikes the large concave mirror of a reflecting telescope where is the light focused?
In front of the mirror
What has a mirror that collects light which is reflected to the eyepiece to show the image?
A Reflecting Telescope.

What type of lens does a reflecting telescope use?
A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.

How many mirrors does a reflecting telescope have?
A reflecting telescope only needs one mirror, the primary mirror which will focus incoming light to a single point. A digital telescope might place the digital recording media directly in front of the reflecting telescope without any additional mirrors (although perhaps some lenses). For practical purposes though, most optical telescope will have a secondary mirror that will either focus light straight back through a hole in the primary telescope mirror, or to the side of the telescope. Some telescopes, especially the large ones in observatories will have several mirrors directing the light path to the observer or recording equipment.
