Question:
Resolving power of a telescope will be more, if the diameter of the objective is:
Resolving power of a telescope will be more, if the diameter of the objective is:
Show Hint
Bigger objective lenses give sharper images.

- larger
- smaller
- it does not depend on diameter
- None of these
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Resolving power: \[ \text{RP} \propto \frac{D}{\lambda} \]
Step 2: Larger diameter improves resolution.
