Re: ray optics
i can't challenge ritu,but i am thinking in another way
size of object as perceived by us depends primarily on size of d image formed on d retina
so answer should be 4
I am thinking it as microscopes just increase the size of image on retina,so object looks bigger(thereby rejecting 1)
simi;lar in case of telescopes,etc
