The resolving power of a telescope whose lens has a diameter of 1.22 m for a wavelength of `5000 Å` is

What is the resolving power of a telescope whose objective lens has a diameter 1.22 m from a wavelength 4000 Å?

Calculate the resolving power of a telescope,whose objective lens has an aperture of 1.0 m for the wave-length of light 500 nm?

Resolving power of a telescope will be more, fi the diameter (a) of the objective is

A telescope, whose objective lens has an apertune of 1 mm for the wavelength of light 500 A, then limiting resolving power of the telescope is
