Question

In microscopy, resolution is a measure of :

• A. The ability to separate two tiny details that are close together
• B. The total magnification power of the microscope
• C. The empty magnification of the microscope
• D. The ability of an electron microscope to determine the presence of a large number of elements

Hint:

Resolution ≠ magnification; it is the ability to distinguish close objects.

Answer 1

The Correct Option is A

Concept: Resolution is the ability of an optical instrument to distinguish between two closely spaced objects as separate entities.

Step 1: Definition of resolution.
Resolution refers to clarity of detail and the minimum distance between two points that can still be distinguished.

Step 2: Understanding Option (A).
Ability to distinguish two close objects clearly is exactly the definition of resolution.
Thus, (A) is correct.

Step 3: Evaluating Option (B).
Magnification only enlarges the image but does not improve clarity or separation.
Thus, incorrect.

Step 4: Evaluating Option (C).
Empty magnification means magnifying without improving resolution.
Thus, incorrect.

Step 5: Evaluating Option (D).
This relates to analytical capability, not resolution.
Thus, incorrect. Final Conclusion:
Hence, the correct answer is option (1).
