Explain the Astronomical telescope ?

Answer Posted / guest

It consist of two convex lenses. These lenses are called
object glass and eye piece respectively. A real, inverted
and diminished object is formally the object at its focus.
This image lies with the focus of the eye piece which acts
as a magnifying galss, producing a virtual, erect, enlarged
image of it. The first image this seen is magnified, but
inverted with respect to the object.

Magnigying power = F/f

Where F is focal length of object glass, and f is focal
length of eye-piece.
