उत्तर
The resolving power of a telescope depends upon the diameter of an objective.
Explanation:
R.P of telescope = `1/(d theta)=a/(1.22lambda)`
Thus, it is clear that a telescope with a large diameter of the objective has higher resolving power. Thus, the resolving power of a telescope depends on the diameter of an objective.
