Vedclass · Answer

(B) In a compound microscope,the objective lens is designed to form a real,inverted,and magnified image of the object.To achieve high magnification,the objective lens must have a very short focal length $(f_o)$ and a small aperture.The eyepiece acts as a simple magnifier and typically has a larger focal length $(f_e)$ compared to the objective lens.Therefore,the condition for a compound microscope is $f_o < f_e$.

The focal length of the objective lens of a compound microscope is
