Vedclass · Answer

(A) simple microscope is essentially a convex lens used to view small objects. To obtain a magnified,virtual,and erect image,the object must be placed between the optical center $(O)$ and the principal focus $(F)$ of the convex lens. When the object is placed in this position,the light rays diverge after refraction,and when traced backward,they form a virtual image on the same side as the object. Therefore,the correct position is between the principal focus and the optical center.

Where should an object be placed to use a convex lens as a simple microscope?
