Question
The diagram above illustrates a compound microscope. Lens 1,called the objective, is placed near the object of interest. Lens2, known as the eyepiece, is placed so that one of its focal pointscoincides with the image produced by the objective.
In order to improve the angular magnification of themicroscope shown above, would you replace the eyepiece (lens 2)with another lens that has a smaller focal length or alarger focal length? Explain your reasoning. The diagram above illustrates a compound microscope. Lens 1,called the objective, is placed near the object of interest.

Explanation / Answer
total magnification=LD/f0fe as magnification is inversely proportional to focal length ofeyepiece magnification will be more when focal length of objectiveand also eyepiece are smaller. so for better magnification focal length of eyepiece should bereplaced by the eyepiece (lens 2) with another lens that hasa smaller focal length .
