Not exactly. A light telescope is a telescope that catches and shows visible light. The main light-gathering piece may either be a lens, in which case you would have a refracting telescope. Or - much more common with the larger telescopes - the main light-gathering piece is a parabolic mirror. In this case, it is a reflecting telescope. The largest refracting telescope is about 1.2 meters in diameter; all larger telescopes - currently up to about 8 meters - are parabolic mirrors.

∙ 13y agoIf the objective lens of a certain refracting telescope and the primary mirror of a certain
Newtonian reflecting telescope both have the same focal length, then a piece of film or
other imaging device at the prime focus of either one will produce images with the same
scale, and the same eyepiece used on either telescope will produce the same magnification.

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.
How many convex lenses does a refracting telescope have?
At least two, but may have many. Depends on the design of the telescope.
What kind of telescope uses both a reflecting mirror and a refracting lens to produce wide angle photos of the sky?
A reflecting telescope has both magnifying mirrors and lenses to focus the image on the eyepiece. A refracting telescope uses only lenses to magnify and focus. A reflecting telescope can be much smaller, because the light can travel through the barrel of the telescope several times, being magnified with each reflection. This is why most large modern telescopes are reflectors.
What are some telescopes names?
The two types are refractor and reflector. In a refracting telescope, the light comes in THROUGH a magnifying LENS where it is REFRACTED (bent) to focus the light into an objective lens. In a reflecting telescope, the light BOUNCES OFF a curved magnifying MIRROR , and then reflected again on a secondary mirror to direct the light into an objective lens. Among the advantages of a reflecting telescope are that in a refracting lens, the thickness of the lens can absorb some of the light, while a mirror reflects all of the light. Additionally, a reflecting telescope can "fold" the telescope into a much more compact instrument, which is essential with especially large devices. A large refracting telescope would be enormously heavy and cumbersome.
Which type of telescope uses a convex lens to increase the size of the image being viewed?
refracting
How do light microscopes differ from refracting telescope?
They don't. They are the same.
How is a radio telescope different from a refracting telescope?
A radio telescope detects light in the form of radio waves and a refracting telescope detects light in the visible wavelengths
Is a telescope with incoming light passing through glass refracting?
refracting
What do you call a telescope that uses a lens to focus light?
It is called a refracting telescope.
What type of telescope does not use visual light energy?
Infrared the answer is a refracting telescope :p
What is the name of the telescope that uses convex lenses to gather and focus light?
Refracting telescope.
What does the objective of a refracting telescope do?
It gathers the light coming from an object.
What is used to focus light in a refracting telescope?
Concave Mirrors
What is a refracting and a reflecting telescope?
A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
Why are reflecting telescope and refracting telescope considered as optical telescope?
"Optical", in this case, simply means that they work with light.
A telescope that uses a set of lenses to gather and focus light from distant objects?
Refracting Telescope.
What are some of the advantages of reflecting telescopes over refracting telescopes?
Size... a reflecting telescope with the same power as a refracting telescope is much shorter. This is because, in the reflecting telescope, the incoming light is bounced off mirrors (often more than once) which means the physical length is much shorter than an equivalent refracting model.
