Compare the functions of the objective lens in a telescope and a microscope?
The objective lens in a microscope is mainly used to magnify an object. In a telescope, the objective lens is mainly used to gather light.
What does the light gathering ability of a telescope depend on?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
What are the lenses called in a reflector telescope?
The lenses used in reflector telescope is the concave lens.
What is the difference between a refracting telescope and a?
A refracting or refractor telescope is a dioptric telescope that uses a lens as its objective to form an image. The refracting telescope design was originally used in spy glasses and astronomical telescopes but is also used in other devices such as binoculars and long or telephoto camera lenses.There are two basic types of telescopes, refractors and reflectors. The part of the telescope that gathers the light, called the objective, determines the type of telescope. A refractor telescope uses a glass lens as its objective. The glass lens is at the front of the telescope and light is bent (refracted) as it passes through the lens. A reflectortelescope uses a mirror as its objective. The mirror is close to the rear of the telescope and light is bounced off (reflected) as it strikes the mirror
What does the simplest optical telescope contain?
It contains an objective lens and a lens in the eyepiece of the telescope.
What type of lens used in telescope?
Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.
A refracting telescope produce an image using an?
A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
How does a refracting telescope differ from other types of telescopes?
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.

What is a type of lens which magnifies an object beginning with t?
telescope

A refracting telescope is a type of optical telescope. It was used in astronomical telescopes and spy glasses. Objective lens are used to produce the image.
Was Galileo's telescope a reflector.?
No: Galileo's telescope was a Galilean refractor, which is to say it has a single large object lens at the top end and a concave eye lens at the other end. This is not a popular type of telescope now because it has a small field of view, and it is only used for cheap telescopes and opera glasses.
What type of lens use in microscope?
Most lenses used to view smaller things is a convex: Telescope, microscope, binoculars, etc.

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.
What does the simplest optical telescope contain?
It contains an objective lens and a lens in the eyepiece of the telescope.
