How does a refracting telescope produce an image?

Answer 1

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).

Answer 2

The 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.

Answer 3

A refracting telescope uses lenses to gather and focus light from distant objects. The objective lens at the front of the telescope collects light and forms an image at the focal point. The eyepiece lens magnifies the image formed by the objective lens, allowing the viewer to see a clear and enlarged view of the object.

Answer 4

A refracting telescope works by bending light through a lens so that it forms an image. It uses a convex glass lens.
