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.
What else can I help you with?
Which structure is used to foucus light in a refelcting telescope?
A curved mirror is used to focus light in a reflecting telescope by reflecting and converging the light rays to a focal point. This mirror can have a concave shape to collect and concentrate light towards the eyepiece for observation.
Does a reflecting telescope gather light with a lens or a mirror?
A reflecting telescope gathers light with a mirror instead of a lens. The mirror reflects light to a focus point where the image is formed. This design eliminates chromatic aberration that can occur with lenses.
At the end of the reflecting telescope is a what mirror?
At the end of the reflecting telescope is a primary mirror. This mirror collects and focuses light from distant objects before reflecting it to a smaller secondary mirror or camera for further magnification or analysis.
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.
What telescope collects light with a mirror?
A reflector telescope collects light with a mirror. The mirror is located at the back of the telescope and reflects the incoming light to a focal point where it is then collected by an eyepiece for viewing.

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 focused?
In front of the mirror

What part of a reflecting telescope would you measure to find the apeture?
To find the aperture of a reflecting telescope, you would measure the diameter of the primary mirror. The aperture of a telescope is the diameter of its primary light-gathering element, which in the case of a reflecting telescope, is the primary mirror.
What has a mirror that collects light which is reflected to the eyepiece to show the image?
A Reflecting Telescope.

What is used in a telescope to reflect light?
Reflecting telescopes use mirrors to collect light.
What telescope has an eyepiece lens and a mirror?
A reflecting telescope has both an eyepiece lens and a mirror. Light enters the telescope and is reflected off the primary mirror to a secondary mirror, which then directs the light to the eyepiece where it is magnified for viewing.
