Which microscope magnification should be used to observe the largest field of view of an insect wing?
(1) 20x
(2) 100x
(3) 400x
(4) 900x

The larger the magnification value, the smaller the field of view. This is because a larger magnification zooms into the object so you can see the small details, but not the whole picture.

On the other hand, the smaller the magnification value, the larger the field of view. For example, you can see the whole sky without a telescope, but if you look at the sky with a telescope that has a magnification, then you can only see a small section of the sky, though more detailed.
