What is the relation between limit of resolution and resolving power of an optical instrument ?

For observing fainter distance objects and for high resolving power which of the following telescope should be used ?

The vertical angle subtended by two points on a glass block at the objective of a microscope is 20^@ .Calculate the minimum distance between the points if they are just resolved when illuminated by light of wavelength 600 nm. What is the increase in resolving power of the instrument if the objective is immersed in oil of refractive index 1.5?

The expression of resolving power of a microscope is inversely proportional to the wavelength lambda used to illuminate the object . Can we have a source with a very small wavelength compare to that of the visible light ?
