Vedclass · Answer

(B) In a compound microscope,the objective lens is placed near the object and must have a short focal length to produce a magnified real image. The eyepiece acts as a simple magnifier and typically has a longer focal length compared to the objective lens. Therefore,the lens with a focal length of $5 \, cm$ serves as the objective,and the lens with a focal length of $20 \, cm$ serves as the eyepiece. Thus,the correct option is $B$.

The compound microscope consists of two convex lenses of $5 \, cm$ and $20 \, cm$ focal length. Which of them will be the objective and the eyepiece?
