Question

Which of the following is correct about resolving power of a Microscope ? A. Limit of Resolution is directly proportional to the numerical aperture.
B. Resolution power of a microscope increases with magnification.
C. The greatest resolution in light microscopy is obtained with the shortest wavelength of light.
D. Limit of resolution is the smallest distance by which two objects can be separated and still be distinguishable.
E. The maximum resolution of a light microscope is \(0.02\, \mu m\).
Choose the correct answer from the options given below :

• A. \(A\) only
• B. \(C \text{ and } D\) only
• C. \(B\) only
• D. \(D \text{ and } E\) only

Hint:

Remember the resolution formula: \[ d = \frac{0.61\lambda}{NA} \] Better resolution occurs with:
• Smaller wavelength
• Higher numerical aperture \[ \text{Light microscope resolution} \approx 0.2\, \mu m \]

Answer 1

The Correct Option is B
