Assertion `:` If objective and eye lenses of a microscope are interchanged then it can work as telescope.
Reason `:` The objective of telescope has small focal length.

Assertion : If objective and eye lens of a mcroscope are interchanged then it can work as telsecope. Reason : The object of telescope has large focal lengths.

A: If objective and eye-piece of compoun microcscope are interchanged, then i becomes a telescope. R: Focal length of objective of telescope i small.

Consider the following statements about a microscope and a telescope 1. Both the eyepiece and the objective of a microscope are convex lenses. 2. The focal length of the objective of a telescope is lerger than the focal length of its eyepiece. 3. The magnification of a telescope increases with the increases in focal length of its objective. 4. The magnification of a microscope increases with the increases in focal length of its objective. Which of the statements given above are correct?
