प्रश्न
How does the resolving power of a telescope change on increasing the aperture of the objective lens? Justify your answer.
उत्तर
The resolving power of a telescope is given by
\[R . P . = \frac{1}{d\theta} = \frac{D}{1 . 22\lambda}\]
On increasing the aperture (D) of the objective lens, the resolving power will increase.
