A refracting telescope works just like a magnifying glass. It uses a convex glass lens (to bend light and bring it into focus. This lens is thicker in the center than it is toward its edges, which bends the light more at the edge of the lens than light coming through the center. This allows all of the light to come together at a focus point. The point of focus is where the image is created.
If someone looks into the eyepiece, a concave lens magnifies the image
Refracting telescopes have two main problems-images are not always clear because the light is being bent and the size of the lens is limited (which limits the power of the telescope).

∙ 9y agoThe big lens at the front, the object lens, focusses parallel rays to a point, so there is a small upside-down image of the target in the focal plane, which you can see if you put a white card there. Normally there isn't a white card there but behind the image there is a small magnifying lens which you look through to see the magnified image.
The amount of magnification (linear) is the ratio of the focal lengths of the object lens and the eye lens.

What does a simple refracting telescope have?
It has a collection of mirrors and lenses - which direct the incoming image to the eyepiece, which is usually set at 90 degrees to the body of the telescope.
What type of telescope is used to view distant land objects?
Any telescope will do this but traditionally the old fashioned brass telescopes were refracting telescopes.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. == ==
What are some things Issac Newton invented and or reinvented?
Newton invented the reflecting telescope which is a a great advance over the refracting telescope. The refracting telescope distorted the image via refraction. Newton invented Calculus, which is the engine of mathematics. Newton invented lens and prisms for light analysis.
What kind of telescope did Galileo invent?
Refracting telescope
Does a reflecting telescope produce an upright image?
The most common type of reflecting telescope produces an inverted image. However, it's possible for a reflecting telescope to produce an upright image, depending on exactly how the optics are arranged.
A refracting telescope produce an image using an?
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.
How many times bigger does the image appear in a refracting telescope?
That will depend on your telescope power.
What type of image is formed by a refracting telescope -?
an enlarged, upside-down virual image.
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]
How does a refracting telescope differ from other types of telescopes?
A refracting telescope is a type of telescope that uses a lens as its objective to form an image. This is different from other type of telescopes because it has a objective lens.
What is a convex lens that focuses light to form an image at the focal point?
A magnifying lens. In a Refracting Telescope, a convex lens focuses light to form an image at the focal point.
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.
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.
Which type of telescope uses a convex lens to increase the size of the image being viewed?
refracting
What does a simple refracting telescope have?
It has a collection of mirrors and lenses - which direct the incoming image to the eyepiece, which is usually set at 90 degrees to the body 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.
Is the difference between a refracting telescope and a reflecting telescope?
A reflecting telescope uses mirrors while refracting telescopes uses lens. The refracting telescope also had chromatic aberration and bad resolution while the reflecting telescope had none of these.
