The question is about the resolving power of optical instruments like telescope and microscope.
It is the ability of the instrument to resolve the images of two points that are close to each other. If dθ is the angular separation, resolving power is given by the formula
R = 1/dθ = D/1.22 λ where Dis the aperture of the objective; λ is the wavelength of the light .
Resolution is the ability of a lens to separate or distinguish between small objects that are close together. Much of the optical theory underlying microscope design was developed by the German physicist Ernst Abbe in the 1870s. The minimum distance (d) between two objects that reveals them as separate entities is given by the Abbe equation, in which lambda () is the wavelength of light used to illuminate the specimen and n sin theta is the numerical aperture (NA). d= .5 x lambda n sin theta
Resolving power is a function of numerical aperture of the objective lens use in the microscope and the wavelength of light . The formula for resolving power is given as , RP= wavelength / (2 x NA) where NA is the numerical aperture.
The ability of an optical device to shownearby points on anobjectas separate images.
This is obviouslyimportant in microscopes andtelescopes.
The clarity of the image in showing two objects as separate.
resolving power
If magnification increases ONLY, then resolving power does not increase. However, if the magnification increased while staying in focus (upgrading resolution and magnification with objective lense), shorter wavelengths are needed to stay in focus with increased magnification to yield the same high resolution as with previous objective lense, so this case, resolving power does increase.
Resolving Power
That will depend whether the microscope is designed to cope with the new wavelength as well as it did with the old. For example, ordinary visible-light microscopes are useless for ultraviolet. The absolute limit to resolving power with perfect optics is about quarter of a wavelength but real microscopes fall short of this.

No
the resolving power of light microscope is 0.2 micrometr
Resolving power of microscope is inversely related to the wavelength of the light used. So shorter the wavelength, greater the resolving power.

help!
BOYYYYYY
Resolving power is the ability of an imaging device to separate points of an object that are located at a small angular distance

I know of at least three. I hope these help: - magnifying power - light gathering power - field of view
