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 telescope uses an eyepiece and an objective lens?
Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.
What kind of telescope's objective is a lens but contains no mirrors?
Refractors use a concave lens to refract the light rays through the main body, off the rectangular prism and into the eyepiece. These telescopes use no mirrors like reflectors (except the triangular prism contains a small mirror but a triangular prism is optional)
Did Galileo design refracting telescopes?
Many historians explain that Galileo was the first person to use a telescope. In 1610 Galileo discovered Saturn's rings. He also observed Jupiter's four moons and viewed the different phases of Venus. This lead to the study of sunspots and various celestial activities. Even though Galileo is credited with being the first to make practical improvements and enhancements to the use of the telescope, he was not the inventor, and therefore not the first person to use a telescope. That person would be Hans Lippershey. Hans Lippershey was born 1570 in Germany, but was raised in Holland. He invented the first refracting telescope in 1608. A lens maker, he designed this telescope from two lenses and applied for a patent, intending that it would be important for the military. He successfully demonstrated the usefulness of his refracting telescope to the military.
Where did Galileo invent the telescope?
Galileo didn't actually invent the telescope, though he was one of the first to use it for astronomical observations. At the time he constructed his first telescopes, he was teaching at the University of Padua in Italy.
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 tool do scientist use to observe distant objects in the sky?
Terrestrial telescope
The type of telescope uses convex lenses to increase the size of the image viewed?
According to scientists, the refracting telescope uses a convex lens which increases the size of an image. The most common use of this telescope is for viewing solar system planets such as Jupiter and Mars.
What type of lens used in telescope?
Most telescopes use refractor lenses. Sometime a telescope will use reflector lenses.
Does salt use conventional lenses like other telescope?
yes i think it does because it is a refracting lens telescope like the telescope build in Yerkes observatory in 1671 .
What kind of telescope focuses light through a transparent lens?
An optical telescope (as distinct from, say, a radio telescope). It's possible that the answer was intended to be "a refracting telescope" but reflecting telescopes use lenses as well.

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.
Does a telescope use a convex lens?
Yes, a telescope typically uses convex lenses to gather and focus light. The objective lens, which is usually convex, collects and refracts light to create an image that can be magnified by the eyepiece lens.
What is the use of reflecting telescope?
a. concave mirror b. a convex lens c. a plane mirror or d. all the above.
