Magnifying power of a compound microscope is high if
- a)the objective has a long focal length and eye-piece has a short focal
- b)the objective has a short focal length and the eye-piece has a long
- c)both objective and eye-piece have short focal lengths
- d)both objective and eye-piece have long focal lengths
Correct answer is option 'C'. Can you explain this answer?

Magnifying power of a compound microscope is high ifa)the objective ha...
Magnifying power of a compound- microscope is given by m=− (lD/f0fe)
where, l is length of tube
D is least distance of clear vision
f0 is focal length of objective
fe is focal length of eyepiece
So, clearly, it can be seen that focal length of objective and eyepiece needs to be decreased so that magnifying power increases.

Understanding Magnifying Power
The magnifying power of a compound microscope is determined by the combination of its objective and eyepiece lenses. Each lens plays a crucial role in magnifying the image of the specimen.
Role of Focal Length
- The focal length of a lens is the distance from the lens at which parallel rays of light converge or diverge.
- A shorter focal length means a greater ability to bend light, resulting in higher magnification.
Objective Lens
- The objective lens is the first lens that light passes through when viewing the specimen.
- A short focal length objective lens produces a larger magnified image of the specimen.
- This lens is responsible for creating a real, inverted image that is then viewed through the eyepiece.
Eyepiece Lens
- The eyepiece (or ocular lens) magnifies the image produced by the objective lens.
- A short focal length eyepiece lens also contributes to higher total magnification.
- It allows the viewer to see the enlarged image more clearly.
Combining Lenses for High Magnification
- When both the objective and eyepiece have short focal lengths, the total magnification increases significantly.
- This is because both lenses work together to enlarge the image: the objective lens creates a larger real image, and the eyepiece magnifies that image further.
Conclusion
- Therefore, the correct answer is option 'C': both objective and eyepiece having short focal lengths yield high magnifying power in a compound microscope.
- This setup provides a clearer and more detailed view of the specimen, essential for microscopic studies.
