# How can the resolving power of a telescope be increased?

#### Resolving power of telescope is defined as the reciprocal of the smallest angular separation between two distant objects whose images are seen separately.

Resolving power of telescope RP=a1.22λ

where a is the diameter of objective lens of telescope.

⟹ RP ∝a

Thus resolving power of telescope can be increased by increasing the diameter of objective lens of telescope.
