convex lens in microscope and concave lens in telescope
The objective lens. Which is the large lens on the front of the 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.
It contains an objective lens and a lens in the eyepiece of the telescope.
A lens.A lens.A lens.A lens.
the three functions of a telescope are the objective lens, the focuser, and the ocular lens
A reflecting telescope is different from a refracting telescope because a reflecting telescope uses a concave lens, a plane mirror, and a convex lens. While a refracting telescope uses two lens.
depends what kind of telescope
The objective lens focuses the light entering a refracting telescope.
The "objective" lens (as opposed to the eyepiece).
spectrum telescope refracting telescope
A reflecting telescope has mirrors, and a refracting telescope has a lens.
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.
A telescope in which the principle optical component is a lens, as opposed to a mirror
In a simple model there are two: the objective lens and the eyepiece lens
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.
EQ indicates that the telescope has an Equatorial mount
None. A refracting telescope uses a lens.
It depends on the type of reflecting telescope.
It is called a refracting telescope.
10mm lens is more powerful than the 20mm 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.
