What is the biggest problem with building a giant refractor?
Grinding a lens to the required precision aw well as the mass of the lens distorting its shape.
How many mm is the Emerson 50x100 Refractor Telescope with Tripod?
The Emerson 50x is 12mm and the 100x is 6mm.
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?
Practically all telescopes which use lenses, normally the refracting type. the Reflector use objective Concave Mirrors, but even these need eyepieces or finder scopes.
Can a telescope refract light?
The human eye is a refractor, but the telescope could be either refractor or a reflector.

What is refractors?
A refractor is a telescope whose principal focusing element is a lens and collects lots of light from a distant object and brings that light, or image, to a point or focus.

What was the first microscope called?
The first microscope was called the "simple microscope" or "single lens microscope". It was developed in the late 16th century and consisted of a single convex lens used to magnify small objects.
