Question:
The magnifying power of a simple microscope can be increased by using
The magnifying power of a simple microscope can be increased by using
Show Hint
Always use short focal length convex lens for higher magnification.
Updated On: Apr 24, 2026
- diverging lens of large radius of curvature
- converging lens of small focal length
- diverging lens of small focal length
- converging lens of large focal length
- diverging lens of large focal length
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
• Magnifying power: \[ M = \frac{D}{f} \]
Step 1: Observation
Magnification inversely proportional to focal length.
Step 2: Conclusion
Smaller $f$ → higher magnification. Final Conclusion:
