Resolving power of a microscope is the reciprocal of the minimum distance (d) between two point objects, which can just be seen through the microscope as separate.
To increase the resolving power, m, q should be large and l should be decreased where
l = the wavelength of the light used to illuminate the object.
q = half angle of the cone of light from the point object kept under objective lens.m = refractive index of the medium between the object and objective lens.
Resolving power of a telescope is the reciprocal of the small angular separation dq between two distant objects whose images are just seen in the telescope as separate.
