The parameter to be increased in order to increase the angular magnification of a simple microscope is
- A aperture of the lens
- B size of the object
- C power of the lens
- D focal length of the lens
Answer & Solution
Correct Answer
(C) power of the lens
Step-by-step Solution
Detailed explanation
Angular magnification: \( M = 1 + \frac{D}{f} \). Power of lens: \( P = \frac{1}{f} \). Thus, \( M = 1 + DP \). To increase \( M \), increase \( P \).
