Vedclass · Answer

(A) The resolving power $(RP)$ of a telescope is defined as the reciprocal of the minimum angular separation between two objects that can be just distinguished by the telescope.It is given by the formula:$RP = \frac{D}{1.22 \lambda}$where $D$ is the diameter of the objective lens and $\lambda$ is the wavelength of light used.From the formula,it is clear that $RP \propto \frac{1}{\lambda}$.Therefore,when the wavelength of light $(\lambda)$ decreases,the resolving power of the telescope increases.
