What are the advantages and disadvantages of a ground based radio telescope?

disadvantages:Refractor telescopes suffer from chromatic aberration, a color distortion that produces a rainbow of colors around an image. Chromatic Aberration can ruin an images appearance. The glass lens is easily broken. Often, the glass lens in a refractor telescope is not perfect and as a result of this imperfection, large refractor telescopes (over 40 inches) do not work properly.

What telescope uses an eyepiece and an objective lens?

A refracting telescope uses an eyepiece and an objective lens. The objective lens gathers and focuses light, while the eyepiece magnifies the image for viewing.

Can a telescope refract light?

Yes, a telescope uses lenses to refract light to form an image. The objective lens refracts and focuses light to form an image at the focal point, which is then magnified by the eyepiece for viewing.
