Do refracting and reflecting telescopes use visible light to view the images?

Those terms are most commonly used for optical telescopes. However, the same design can be used for non-visible frequencies; for example, radio telescopes of the "satellite dish" variety are essentially reflecting telescopes.

avoided. But the main job of a lens is to refract the light that passes through it.

∙ 15y agoThere are two basic types of telescopes; refracting and reflecting.
Refractor telescopes use lenses to magnify the image, while reflector telescopes use curved mirrors to magnify the image.
Both types of telescopes use eyepiece lenses to focus the image, but only refractor telescopes use the lens to magnify the image.
Refractor telescopes are small and portable, but all really powerful astronomical telescopes are reflecting.

∙ 14y agoThe light that goes through the lens of telescope is bent, or "refracted", to create the image that we see.
Other types of telescopes, called "reflecting telescopes" or just "reflectors" use curved mirrors to magnify and focus the light. In these cases, the light bounces from one mirror to another, before going THROUGH a refracting lens to focus the image.

uses a concave parabolic mirror to accomplish the same purpose.

How do telescopes for invisible wavelengths differ from those for visible light?
Visible Light telescopes use mirrors or lenses. The images are viewed by the naked eye. Telescopes operating in invisible wavelengths use Electromagnetic sensors. The data is then converted into an image that can be viewed by us.
What are the similarities between a refracting telescope and reflecting telescope?
The two major telescopes are refractive and reflective. Refractive uses two lenses and a 45 degree mirror. Lense, mirror lens. Reflective uses an open tube.light come in and strikes a concave mirror. Reflects back to the opening where a flat 45 degree mirror reflects light into an eyepiece lense that is near the opening. Images in a reflective telescope are backward without the use of an erecting prism. Further research for you, Dobsonian, Cassegrain.
How do telescopes and the electromagnetic spectrum work together to help us explore space?
Telescopes are used to observe and magnify images in outer space. The electromagnetic spectrum consists of many wavelengths, which constitute visible light, infrared, microwave, and X-ray radiation. Telescopes can be manufactured to view these certain types of radiation.
Why are reflecting optical telescopes important?
In general, reflecting telescopes can give you more light collection than refracting telescopes, and they can be designed to have greater focal length in more compact bodies. Light collection is the single most important factor in a telescope's ability to produce images of good resolution.
What do microscopes telescopes and binoculars all use to magnify images?
lenses
An object that readily transmits light without distorting the images?
refracting telescopes
What type of image is formed by reflecting telescope?
the images are clear and can be focused unlike a refracting telescope witch sags under its own weight causing images to be distortedAny telescope forms a real image. Otherwise, it's pretty useless as a telescope.Comments: Refracting telescopes are good these days. They should not sag. Also, Galileo's telescope formed a virtual image, and that wasn't useless.An important point about the image in a reflecting telescope is that it is inverted, as well as being a real image.
Is a light telescope the same as a refracting telescope?
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.
What are two problems with refracting telescopes?
Images are not always clear because the light is being bent.The size of the lens is limited which limits the power of the telescope.
Why are mirrors used in a telescope?
Mirrors are used in a telescope because they bounce images off of them instead of bending images like refracting telescopes. This ensures that the image is focuses. If you were using a refracting telescope (no mirror) the colours would be bent at different times making an unfocused image.
How do telescopes for invisible wavelengths differ from those for visible light?
Visible Light telescopes use mirrors or lenses. The images are viewed by the naked eye. Telescopes operating in invisible wavelengths use Electromagnetic sensors. The data is then converted into an image that can be viewed by us.

How are images transmitted back to Earth by a refracting telescope?
If a telescope is in orbit it must have its results converted to radio waves to transmit back to Earth. It doesn't matter what type of telescope it is. Most research telescopes are reflectors.
What are the similarities between a refracting telescope and reflecting telescope?
The two major telescopes are refractive and reflective. Refractive uses two lenses and a 45 degree mirror. Lense, mirror lens. Reflective uses an open tube.light come in and strikes a concave mirror.

Why can the hubble space telescope make images in visible light that are much better than images made by the telescopes on earth?
There is minimal atmospheric disturbance up where the Hubble orbits. Down here on Earth we have to contend with the atmosphere.
Does a telescope form a real image?
Yes. Both the objective lens in a refracting telescope and the main mirror in a reflecting telescope form real images at the prime focus. A frame of photo film or a CCD placed at that spot will capture the image.
