Question

Why the aperture of the objective of microscope should be small ?​

Answer 1

Answer:

Because

Explanation:

So the smallest thing that you can see with a light microscope is about 200 times smaller than the width of a hair. Bacteria are about 1000 nanometers in size. The reason we can't see anything smaller is because these microscopes use light.

Answer 2

hi friend,

here is your answer

Answer:

if aperture is large then light Ray coming from object expands

Explanation:

The microscope is used in sighting small objects situated nearby. If aperture is large then light ray coming from object expands. So intensity becomes small. If aperture is small then light coming from object expends in small aperture, as a result object is seen more bright. So, aperture is kept small.
