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 method did Herschel use to discover the new planet?
William Herschel discovered the planet Uranus, using a homemade telescope in the back garden of his house in Bath (England). It was also the first discovery of a planet made using a telescope. -------------------- a telescope
How can people see sun spots?
First of all you should have eye protection and then project an image of the Sun through a telescope or binoculars onto a white screen -- paper plates, walls and sidewalks all work nicely. On the screen you should see a bright circle of light. This is the disc of the Sun. Adjust the distance between the screen and the telescope until the disk is about the size of a small paper plate. The image will probably be blurred; focus your telescope until the circle becomes sharp. Using this method you can see considerable detail in and around sunspot groups.
What kind of telescope is the hubble telescope?
HST is a Cassegrain reflecting telescope using the Ritchey–Chrétien design, with an aperture of 7.9' (2.4m). It has observational ability in the Ultraviolet, Infrared, and Visible light spectrums.
What is a sentence using astronomer?
The astronomer studied distant galaxies using a powerful telescope.
How did people first investigate the planet?
people first investigated the planets using 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.
Telescope that uses several mirriors to combine and focus light?
A reflecting telescope forms an image by using a combination of curved mirrors to focus light. It was invented as an alternative to the refracting telescope.
What other things were developed using the refracting telescope design?
the reflecting telescope was!!
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.
Galileos telescope designs using lenses were examples of?
Refracting telescopes :}
What telescope using lenses to make an image?
The reflecting telescope
What tool did Galileo use to discover things about space?
In his early career: No telescopes. A log to track planets. Sea-faring devices such as the sextant Later in life: In 1609 Galileo started using the telescope on the 'heavens' Kepler used the Galilean telescope until 1611 he re-invented the refracting telescope (now known as the Keplerian telescope)
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.
What uses are there for a relfecting telescope?
By using a Reflective telescope the viewer sees the image of a normal telescope, reflected on a mirror, which is viewed through a microscope, by doing this the telescope doubles it's viewing ability
Why did the invention of a reflecting telescope help people to see more than a lens telescope?
There are a number of advantages with a reflecting telescope but the most favourable is the fact that it uses a curved mirror which 'reflects' the image as opposed to a refractor which 'refracts' the image. In short, 'white light' is made up from all of the colours of the rainbow. When using a reflecting telescope, the mirror deflects the entire light make-up in one go so that a sharp focal point can be defined. With a refracting telescope, each individual light colour refracts at a different angle meaning that if you place the focusing lens in position for say violet, it will be out of focus for the other six colours.
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.
A sentence using the word achromatic?
The distracting violet fringing of the image in the telescope was limited by the use of an achromatic lens system.
