The telescope described is an optical telescope. If the primary optic is a mirror, it's a reflector, and it the primary optic is a lens, it's a refractor.

Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
What does the simplest optical telescope contain?
It contains an objective lens and a lens in the eyepiece of the telescope.
The primary mirror of a reflecting telescope is what kind of shape?
It is a paraboloid, which focusses the light from a star down to a single point which can then be looked at through the eye lens or eyepiece.
What was the two lenses called on the refracting telescope?
Front lens - objective Back lens - eyepiece
What is a barlow lens on a telescope?
A barlow lens increases the magnification of the eyepiece usually by a factor of two.
What is the power of the eyepiece?
The magnification, or power, at which a telescope is operating is a function of the focal length of the telescope's main (objective) lens (or primary mirror) and the focal length of the eyepiece employed.
Which part of a refracting telescope forms the image?
Eyepiece, Primary Mirror, Secondary Mirror, Prime Focus.
Which lens is the second lens that magnifies the object?
The eyepiece of the telescope doesn't magnify the object, but it does magnifythe real image of the object that forms at the focus of the primary lens or mirror.
What does the simplest optical telescope contain?
It contains an objective lens and a lens in the eyepiece of the telescope.
What is the lens that is the larger lens in a refracting telescope?
The "objective" lens (as opposed to the eyepiece).
Does a eyepiece of a telescope have a lens?
A telescope eyepiece usually has 2 lenses in an astronomical telescope, and it is designed to give a magnified view of the virtual image produced at the focal point of the main lens.
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.
What is a telescope that uses a mirror to collect light emitted by distant or faint objects?
This type of telescope is often referred to as a Schmidt-Cassegrain telescope, and can be short and wide. They have an eyepiece that extends at a right angle from the body, and have a disk in the middle of the lens, behind which is the mirror.
Are lens part of a telescope?
-- A refracting telescope must have a lens, otherwise it's not a refracting telescope. -- A reflecting telescope can be constructed without any lens, but if you intend to look through it, then you'll use a little lens for the eyepiece.
The primary mirror of a reflecting telescope is what kind of shape?
It is a paraboloid, which focusses the light from a star down to a single point which can then be looked at through the eye lens or eyepiece.
What was the two lenses called on the refracting telescope?

What is a barlow lens on a telescope?
A barlow lens increases the magnification of the eyepiece usually by a factor of two.
