Discuss the resolving power of a microscope:-With luminous point objects.

Define resolving power of a microscope .

The resolving power of a microscope, with a pair of non-luminous objects is

The limit of resolution of a microscope with self luminous point objects is

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 ?

The magnifying power of simple microscope is

Derive an expression for Resolving Power of a Microscope.

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?
