Question
Resolving power of a telescope increases with:
✓

Answer

  1. Increase in aperture of objective
Explanation:
Resolving power of a telescope:
$\text{R}=\frac{\text{a}}{1.22\lambda}$
where, a is diameter of the objective
so, R increases when a is increased and a increases when aperture of objective is increased.
