Question

The resolving power of a telescope depends upon the...............

(a) length of the telescope

(b) focal length of an objective

(c) diameter of an objective

(d) focal length of an eyepiece

Solution

(c) diameter of an objective

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.

  Is there an error in this question or solution?
