The resolving power of a telescope depends on a diameter of the telescope's light-gathering appratus, or objective lens is the first lens the light passes through.
Resolution

= \frac{Wavelength ( λ )}{Diameter ( D )}

If both assertion and reason are true and reason is the correct explanation of assertion.

If both assertion and reason are true but reason is not the correct explanation of assertion.

If assertion is true but reason is false.

If both assertion and reason are false.

The resolving power of a telescope depends on a diameter of the telescope's light-gathering appratus, or objective lens is the first lens the light passes through. Resolution = Diameter (D) Wavelength (λ)​
