Give any three differences between a compound microscope and a telescope.

Explanation

The focal length and the size of the objective will be less than the eye piece in the case of a compound microscope whereas in the case of a telescope, the focal length of the objective and its size will be larger than in the microscope.
The magnification in the case of a compound microscope is `m=(L)/(-f_(0))((D)/(f_(e)))`, whereas in the case of a telescope `m=(f_(0))/(f_(e))` for image at infinity and .L. is the length of the tube of the microscope.
The length of the telescope `=L=f_(0)+f_(e)` and the length of compound microscopeis `v_(0)+f_(e)` where `v_(0)` is the image distance obtained in the case of refraction through the object lens.
