Concave lenses are used as eye lens of _______ telescope.

Assertion:- In modem microspore multicomponent lenses are used for both objective and eye piece. Reason:- Multicomponent lenses increase the magnification.

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.
