$\Large\bold\star\underline{\underline\textbf{Simple microscope\:}}$

→ A convex lens of small focal length is called simple microscope.

$\Large\bold\star\underline{\underline\textbf{Principle\:}}$

→ When an object is placed between optical centre and focus of a convex lens, it produces a virtual, erect and magnified image on the same side of the lens.

$\Large\bold\star\underline{\underline\textbf{Working\:}}$

→ Check the attachment first.

→ Consider a convex lens of focal length f. Let object AB be placed between focus (F) and optical centre (C) of the lens. After refraction the rays appear to come from point B', so A'B' is the image of object AB. The image is erect, virtual and magnified. The position of image is so adjusted that final image is formed at least distance of distinct vision (D).
