Vedclass · Answer

(B) The resolving power of a telescope is given by the formula: $RP = \frac{d}{1.22 \lambda}$,where $d$ is the diameter of the objective lens (aperture) and $\lambda$ is the wavelength of light.From this relation,it is clear that the resolving power is directly proportional to the aperture: $RP \propto d$.Therefore,a larger aperture is used to increase the resolving power of the telescope,allowing it to distinguish between two closely spaced objects.
