Homework Statement


Which forms the larger image on the retina of your eye: a 43 ft tree seen from a distance of 210 ft, or a 12 in flower viewed from a distance of 2.0 ft?


Homework Equations


none?


The Attempt at a Solution


I don't really understand how you would go about working this out, but using my common sense, I'd imagine that it is the flower. However, I was wondering if anybody could guide me if there is in fact a particular way of figuring this out? Thanks

Assume the distance from the lens to the image is the same
Then it's just a question of which triangle has a larger angle.
