    Telescopes have three functions

    1 to collect more light

    2 To resolve close objects

    3 To magnify.

    Explanation:

    To collect more light we have to build large sized mirrors ... Then only we can see very faint objects.

    To separate two close objects a also we need large aperture

    So by making large telescopes we can see more faint objects and more deeper into universe ...
